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. #ripplefactor #trick #onlineexamcentre #halfwaverectifier #fullwaverectifier #electrical #concept #technical #edu #engineering #science #physics #technician

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. #efficiency #rectifier #onlineexamcentre #tricks #electricaltricks #electricalformula #gk trick

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. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, stacks of copper and selenium oxide plates, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switche

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.

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.
