KAIC Lab #1: Understanding Ripple Voltage Based on Different Types of Capacitors

From our KAIC lab, William demonstrates how four different capacitor types affect the ripple voltage on a boost or buck regulator. Each technology of capacitors is compared using the KAIC-RCE-001 board, which uses the same output capacitance bank at the output of a switching regulator. However, the ESR and ESL differences of each technology cause a different output ripple voltage.

Why Capacitive Power Supply should be avoided
 
11:28
Capacitive Power Supplies are a dirty cheap solution to feed simple low power devices directly from Mains, but the drawbacks are way more than the benefits in many cases. In this video I'll try to show that with a practical experiment. In short, lack of isolation, low efficiency and a power factor close to zero should be the main reasons to suggest electronic engineers to avoid this typology of circuit. In this video I've tested an actual circuit, and described in details how it works and why it is so poor in efficiency and power factor.

Full Wave Bridge Rectifiers
 
29:02
This electronics video tutorial provides a basic introduction into full wave bridge rectifiers which are used to convert an AC sine wave signal into a pulsating DC signal. The electronic components used in this type of rectifier circuits are a transformer, 4 diodes, and a load resistor. To reduce the ripple voltage creating a smooth steady DC output signal - you should a shunt capacitor, an inductor, and a zener diode. The shunt capacitor will help to reduce voltage variations while the inductor will reduce variations in current. The zener diode serves as a voltage regulator.

Higher voltage versions are also available. The Effective Impedance (Z), Rectance (X) and the mains frequency (50 – 60 Hz) are the important parameters to be considered while selecting the capacitor. The reactance (X) of the capacitor (C) in the mains frequency (f) can be calculated using the formula: X = 1 / (2 ¶ fC ) For example the reactance of a 0.33µF capacitor running in the mains frequency 50Hz will be: X = 1 / {2 ¶ x 50 x 0.33 x( 1 / 1,000,000) } =9645.75 Ohms 0r 96.6 Kilo ohms. Rectance of the capacitor 0.33 uF is calculated as X = 1/2Pi*f*C Where f is the 50 Hz frequency of mains and C is the value of capacitor in Farads. That is 1 microfarad is 1/1,000,000 farads. Hence 0.33 microfarad is 0.33 x 1/1,000,000 farads. Therefore the rectance of the capacitor appears as 9645.75 Ohms 0r 96.6 Kilo ohms..To get current I divide mains Volt by the rectance in kilo ohm.That is 230 / 96.6 = 23.80 mA. Effective impedance (Z) of the capacitor is determined by taking the load resistance (R) as an important parameter. Impedance can be calculated using the formula: Z = √ R + X Suppose the current in the circuit is I and Mains voltage is V then the equation appears like: I = V / X The final equation thus becomes: I = 230 V / 96.6 = 23.80 mA. Therefore if a 0.33 uF capacitor rated for 230 V is used, it can deliver around 23 mA current to the circuit. But this is not sufficient for many circuits. Therefore it is recommended to use a 470 nF capacitor rated for 400 V for such circuits to give required current. X Rated AC capacitors – 250V, 400V, 680V AC x rated ac capacitors Table showing the X rated capacitor types and the output voltage and current without load capacitor and current Rectification Diodes used for rectification should have sufficient Peak inverse voltage (PIV). The peak inverse voltage is the maximum voltage a diode can withstand when it is reverse biased. 1N4001 diode can withstand up to 50 Volts and 1N4007 has a toleration of 1000 Volts. The important characteristics of general purpose rectifier diodes are given in the table. DC Smoothing A Smoothing Capacitor is used to generate ripple free DC. Smoothing capacitor is also called Filter capacitor and its function is to convert half wave / full wave output of the rectifier into smooth DC The capacitance value determines the amount of ripples that appear in the DC output when the load takes current. Voltage Regulation Zener diode is used to generate a regulated DC output. A Zener diode is designed to operate in the reverse breakdown region. If a silicon diode is reverse biased, a point reached where its reverse current suddenly increases. The value of R can be calculated using the formula: R = Vin – Vz / Iz Where Vin is the input voltage, Vz output voltage and Iz current through the Zener In most circuits, Iz is kept as low as 5mA. If the supply voltage is 18V, the voltage that is to be dropped across R to get 12V output is 6volts. If the maximum Zener current allowed is 100 mA, then R will pass the maximum desired output current plus 5 mA . So the value of R appears as: R = 18 – 12 / 105 mA = 6 / 105 x 1000 = 57 ohms Power rating of the Zener is also an important factor to be considered while selecting the Zener diode. According to the formula P = IV. P is the power in watts, I current in Amps and V, the voltage. So the maximum power dissipation that can be allowed in a Zener is the Zener voltage multiplied by the current flowing through it. For example, if a 12V Zener passes 12 V DC and 100 mA current, its power dissipation will be 1.2 Watts. So a Zener diode rated 1.3W should be used. The drawback of the Capacitor power supply includes No galvanic isolation from Mains.So if the power supply section fails, it can harm the gadget. Low current output. With a Capacitor power supply. Maximum output current available will be 100 mA or less.So it is not ideal to run heavy current inductive loads. Output voltage and current will not be stable if the AC input varies.
