The output of a rectifier is consists of a dc component and an ac component. This ac component is undesirable and cause for the pulsations in the rectifier output.
So the ac component present in the pulsating output i.e. in the rectifier output is known as Ripple.
Ripple Factor:-
The ratio of r.m.s. value of a.c. component to the d.c. component in the rectifier output is known as ripple factor i.e.
Ripple factor = r.m.s. value of a.c component / value of d.c. component=Iac/Idc
The ripple factor is a measure of the quality of the rectification of an AC current.
The DC output of an ideal full wave rectifier should be a "straight line" (i.e. the output should have a constant value), but due to imperfections in the rectifier design or implementation the result has "ripples" caused by an undesired AC component.
The ripple factor compares the rms value of the AC component with the value of the DC output as an indication of how "deep" those "ripples" are.
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) value of the ripple voltage to the absolute value of the DC component of the output voltage, usually expressed as a percentage. However, ripple voltage is also commonly expressed as the peak-to-peak value.
Ripple voltage is an alternating (AC) voltage which is a constituent part of a composite voltage waveform with a constant DC component (offset) which may be positive or negative, but for analysis is usually considered to be an absolute value. The ripple component is often small relative to the DC component, but in absolute terms, ripple (as in the case of HVDC transmission systems) may be thousands of volts. Ripple itself is a composite (non-sinusoidal) waveform consisting of harmonics of some fundamental frequency which is usually the AC line frequency of 50/60Hz, but in the case of switched-mode power supplies, the fundamental frequency can be tens of kilohertz to megahertz. The characteristics and components of ripple depend on its source: there is single-phase half- and full-wave rectification, and three-phase half- and full-wave rectification. Rectification can be controlled (uses Silicon Controlled Rectifiers (SCRs) or uncontrolled (uses diodes). There is in addition, active rectification which uses transistors.
Various properties of ripple voltage may be important depending on application: the equation of the ripple for Fourier analysis to determine the constituent harmonics; the peak (usually peak-to-peak) value of the voltage; the root mean square (RMS) value of the voltage which is a component of power transmitted; the ripple factor γ, the ratio of RMS value to DC voltage output; the conversion ratio (also called the rectification ratio or "efficiency") η, the ratio of DC output power to AC input power; and form-factor, the ratio of the RMS value of the output voltage to the average value of the output voltage. Analogous ratios for output ripple current may also be computed.
An electronic filter with high impedance at the ripple frequency may be used to reduce ripple voltage and increase or decrease DC output; such a filter is often called a smoothing filter.
The initial step in AC to DC conversion is to send the AC current through a rectifier. The ripple voltage output is very large in this situation; the peak-to-peak ripple voltage is equal to the peak AC voltage minus the forward voltage of the rectifier diodes. In the case of a SS silicon diode, the forward voltage is 0.7V; for vacuum tube rectifiers, forward voltage usually ranges between 25 and 67V (5R4). The output voltage is a sine wave with the negative half-cycles inverted.

What is half wave rectifier:
The half wave rectifier is the circuit designed using the diode which is used for converting the AC voltage signal into the DC voltage.
The half wave rectifier only passes the one half of the input sine wave (either positive or negative) and rejects the other half.
The output of the half wave rectifier is pulsating DC. The ripple in the output waveform can be reduced using the filter.
To remove or reduce the ripple from the output waveform, the RC time constant of the filter circuit should be much larger than the time period of the half wave rectifier.

Here described how the connections are made for finding the ripple facor of a halfwave rectifier.
We need a step down transformer, resistors, capacitor, bread board, digital multimeter, and a power supply
1.A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier.
2.A widely used application of this feature and diodes in general is in the conversion of an alternating voltage ( AC ) into a continuous voltage ( DC ). In other words, Rectification.
But small signal diodes can also be used as rectifiers in low-power, low current (less than 1-amp) rectifiers or applications, but where larger forward bias currents or higher reverse bias blocking voltages are involved the PN junction of a small signal diode would eventually overheat and melt so larger more robust Power Diodes are used instead.
The power semiconductor diode, known simply as the Power Diode, has a much larger PN junction area compared to its smaller signal diode cousin, resulting in a high forward current capability of up to several hundred amps (KA) and a reverse blocking voltage of up to several thousand volts (KV).
Since the power diode has a large PN junction, it is not suitable for high frequency applications above 1MHz, but special and expensive high frequency, high current diodes are available. For high frequency rectifier applications Schottky Diodes are generally used because of their short reverse recovery time and low voltage drop in their forward bias condition.
Power diodes provide uncontrolled rectification of power and are used in applications such as battery charging and DC power supplies as well as AC rectifiers and inverters. Due to their high current and voltage characteristics they can also be used as free-wheeling diodes and snubber networks.
Power diodes are designed to have a forward “ON” resistance of fractions of an Ohm while their reverse blocking resistance is in the mega-Ohms range. Some of the larger value power diodes are designed to be “stud mounted” onto heatsinks reducing their thermal resistance to between 0.1 to 1oC/Watt.
If an alternating voltage is applied across a power diode, during the positive half cycle the diode will conduct passing current and during the negative half cycle the diode will not conduct blocking the flow of current. Then conduction through the power diode only occurs during the positive half cycle and is therefore unidirectional i.e. DC as shown.
3. Half Wave Rectification
A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier.
The power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the AC supply in order to convert it into a DC supply. Then this type of circuit is called a “half-wave” rectifier because it passes only half of the incoming AC power supply as shown below.
4. During each “positive” half cycle of the AC sine wave, the diode is forward biased as the anode is positive with respect to the cathode resulting in current flowing through the diode.
Since the DC load is resistive (resistor, R), the current flowing in the load resistor is therefore proportional to the voltage (Ohm´s Law), and the voltage across the load resistor will therefore be the same as the supply voltage, Vs (minus Vf), that is the “DC” voltage across the load is sinusoidal for the first half cycle only so Vout = Vs.
During each “negative” half cycle of the AC sinusoidal input waveform, the diode is reverse biased as the anode is negative with respect to the cathode. Therefore, NO current flows through the diode or circuit. Then in the negative half cycle of the supply, no current flows in the load resistor as no voltage appears across it so therefore, Vout = 0.
The current on the DC side of the circuit flows in one direction only making the circuit Unidirectional. As the load resistor receives from the diode a positive half of the waveform, zero volts, a positive half of the waveform, zero volts, etc, the value of this irregular voltage would be equal in value to an equivalent DC voltage of 0.318 x Vmax of the input sinusoidal waveform or 0.45 x Vrms of the input sinusoidal waveform.
Then the equivalent DC voltage, VDC across the load resistor is calculated as follows.

In this video, the center tapped full wave rectifier and full wave bridge rectifier has been explained. The video also includes a brief discussion about the different Full wave rectifier parameters like Peak Inverse Voltage (PIV), ripple factor, efficiency, Average and RMS voltage etc.
By watching this video, you will learn the following topics:
0:20 Introduction to Full-wave Rectifier
2:21 Center tapped full wave rectifier
6:16 Peak Inverse Voltage of Center tapped Full-wave Rectifier
8:04 Full-wave Bridge Rectifier
10:34 Peak Inverse Voltage of Full-wave Bridge Rectifier
12:07 Full wave rectifier with RC filter (Ripple voltage and Ripple factor)
What is Full wave rectifier:
The full wave rectifier is a very useful circuit for AC to DC conversion and it is designed using the diodes.
Unlike the half-wave rectifier, the full wave rectifier gives output during both half cycles. Hence, the average or DC value of the output signal is more than the signal which is rectified using a half-wave rectifier.
In this video, the following full wave rectifier circuits have been explained.
1) Center tapped full wave rectifier
2) Full wave bridge rectifier
The output of the Full wave rectifier is pulsating DC. The ripple in the output waveform can be reduced using the filter.
To remove or reduce the ripple from the output waveform, the RC time constant of the filter circuit should be much larger than the time period of the Full wave rectifier.
Parameters of the Full wave rectifier:
Average Value: 2Vm / π
RMS Value: Vm/√2
Ripple Factor: 0.48
Efficiency: 81.2 %
PIV: 2Vm (Center tapped Full-wave Rectifier)
PIV: Vm (Full wave Bridge Rectifier)
Output Frequency: 2f

this video is about trick to remember the value of half wave rectifier and full wave rectifier.
after watching this video you will be able to give direct value in mcq typoe exam.
efficiency in rectifiers is equal to the ratio of output DC power (i.e Vdc*Idc) to the input power from the AC supply (i.e Irms^2.R)
efficiency of half wave rectifier is very low its approx 40.5 percent, because there is presence of very high magnitudes of ripples.
for full wave rectifier ripple factor is very less and that’s why efficiency is quite high i.e approx 81.2 percent .
Efficiency can be improved with the use of smoothing circuits which reduce the ripple and hence reduce the AC content of the output. Three-phase rectifiers, especially three-phase full-wave rectifiers, have much greater efficiencies because the ripple is intrinsically smaller.

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.

Voltage regulation has different meanings in different aspects. When we talk about voltage regulation e.g. for a ceiling fan, we often come across term 'regulator' , it literally means change in output voltage. regulation means adjusting voltage level according to our requirements

Half Wave Rectifier
In Half Wave Rectifiertype, only one diode is used. Generally, a step-down transformer is used to provide the required secondary voltage. The transformer isolates the load from the line. This reduces the possibility of electric shock.In the positive half cycle of secondary voltage, the diode is forward biased for voltages greater than the offset voltage. The offset voltage is 0.7 V for silicon diodes and 0.3 V for germanium diodes. This produces a half sine wave of voltage across the load resistor.
In the negative half cycle, the diode is reverse biased. The load current drops to zero.
The load current is always in the same direction. This provides rectification.
Average Voltage = Vdc = Vp/π = 0.318 Vp
Where, Vp = peak value of voltage across secondary. The value of direct current, the diode can handle is called as ‘Current rating of diode’ (Io).
Peak Inverse Voltage – In the negative half – cycle, the diode is reverse-biased. All secondary voltage appears across the diode. The maximum negative (reverse) voltage appearing across the diode is called the ‘Peak Inverse Voltage’ (PIV). To avoid break down, the PIV must be less than PIV rating of the diode.
For half wave rectifier PIV = Vp.
Maximum efficiency of half wave rectifier is 40.6 %.
Advantages and Disadvantages of Half wave rectifier:
A half wave rectifier is rarely used in practice. It is never preferred as the power supply of an audio circuit because of the very high ripple factor. High ripple factor will result in noises in input audio signal, which in turn will affect audio quality.
Advantage of a half wave rectifier is only that its cheap, simple and easy to construct. It is cheap because of the low number of components involved. Simple because of the straight forwardness in circuit design. Apart from this, a half wave rectifier has more number of disadvantages than advantages!
Disadvantages of Half wave rectifier:
1. The output current in the load contains, in addition to dc component, ac components of basic frequency equal to that of the input voltage frequency. Ripple factor is high and an elaborate filtering is, therefore, required to give steady dc output.
2. The power output and, therefore, rectification efficiency is quite low. This is due to the fact that power is delivered only during one half cycle of the input alternating voltage.
3. Transformer utilization factor is low.
4. DC saturation of transformer core resulting in magnetizing current and hysteresis losses and generation of harmonics.
The DC output available from a half-wave rectifier is not satisfactory to make a general power supply. However it can be used for some applications like battery charging.

Half Wave Rectification
A rectifier is a circuit which converts the Alternating Current(AC) input power into a Direct Current (DC) output power.
The input power supply may be either a single-phase or
Half Wave Rectifier.
The power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the AC supply in order to convert it into a DC supply. Then this type of circuit is called a “half-wave” rectifier because it passes only half of the incoming AC power supply
During each “positive” half cycle of the AC sine wave, the diode is forward biased as the anode is positive with respect to the cathode resulting in current flowing through the diode.
Since the DC load is resistive (resistor, R), the current flowing in the load resistor is therefore proportional to the voltage (Ohm´s Law), and the voltage across the load resistor will therefore be the same as the supply voltage, Vs(minus Vf), that is the “DC” voltage across the load is sinusoidal for the first half cycle only so Vout = Vs.
During each “negative” half cycle of the AC sinusoidal input waveform, the diode is reverse biased as the anode is negative with respect to the cathode. Therefore, NO current flows through the diode or circuit. Then in the negative half cycle of the supply, no current flows in the load resistor as no voltage appears across it so therefore, Vout = 0.
The current on the DC side of the circuit flows in one direction only making the circuit Unidirectional. As the load resistor receives from the diode a positive half of the waveform, zero volts, a positive half of the waveform, zero volts, etc, the value of this irregular voltage would be equal in value to an equivalent DC voltage of 0.318 x Vmax of the input sinusoidal waveform or 0.45 x Vrms of the input sinusoidal waveform.

Introduction :
We can judge the performance of HWR (Half Wave Rectifier) by the Ripple Factor (RF) Parameter.
RF is parameter to measure AC & DC component.
RF Significance in case of Rectification:
The less the Vac i.e. the AC component of the Voltage, the more the more good the rectifier.
RF for all waves as:
Ripple Factor(RF)=(AC component of Voltage (Vac) )/(DC component of Voltage(Vdc))
Idealialy: RF = 0 i.e. the Vac = 0 and Vdc ≠ 0
RMS Value :
Its defined as the DC equivalent value in AC circuit i.e. 0.707 0r ((1)⁄(√2)) V DC in AC Circuit = 1 V in DC Circuit.

Rectifier is an electronic device that converts an alternating current to a direct current by suppression or inversion of alternate half cycles. Rectifiers are most often made of a combination of diodes, which allow current to pass in one direction only.
Half wave Rectifier
In half wave rectification, the rectifier conducts current only during the positive half cycle of input AC supply. The negative half cycles of AC supply are suppressed no voltage appears across the load. Therefore the current always flows in one direction through the load through every half cycle.
Full wave Rectifier
A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output by reversing the negative (or positive) portions of the alternating current waveform. The positive (or negative) portions thus combine with the reversed negative (or positive) portions to produce an entirely positive (or negative) voltage/current waveform. For single-phase AC, if the transformer is center-tapped, then two diodes back-to-back (i.e. anodes-to- anode or cathode-to-cathode) form a full-wave rectifier.
Full-wave rectification converts both polarities of the input waveform to DC (direct current), and is more efficient. However, in a circuit with a non-center tapped transformer, four diodes are required instead of the one needed for half-wave rectification. This is due to each output polarity requiring two rectifiers each, for example, one for when AC terminal 'X' is positive and one for when AC terminal 'Y' is positive.
Ripple Factor
The output voltage (or load current) of a rectifier consist of two components namely DC component and AC component. The AC component present in the output is called a ripple. Smaller the ripple more effective will be the rectified.
Voltage Regulation
Domestic, commercial and industrial loads demand a nearly constant voltage supply. It is, therefore, essential that the output voltage of a transformer stays within narrow limits as load and its power factor vary. The leaky reactance is the chief cause of voltage drop in a transformer and must be kept as low as possible by design and manufacturing techniques.
PROCEDURE
1. Connections are given as per the circuit diagram (Half Wave Rectifier) .
2. Note the amplitude and time period of rectified output.
3. Measure Vdc and Vrms.
4. Calculate the ripple factor.
5. Draw the graph for voltage versus time.
6. Repeat the same procedure for Full Wave Rectifier.

A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the Half Wave Rectifier.
The power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the AC supply in order to convert it into a DC supply. Then this type of circuit is called a “half-wave” rectifier because it passes only half of the incoming AC power supply
