I would like to reduce the ripple to 500 mV. I found a formula for three phase rectifiers, but I am not sure if it is correct, because the value is too high. The formula I found is: C = I/6fVpp, where ''I'' is the current, ''f'' is the line frequency, and ''C'' is …
Capacitor Basics: How do Capacitors Work?
Capacitor: In some single phase motors, a capacitor is used to provide an additional phase shift to the motor windings. This helps to improve the starting torque and efficiency of the motor. The capacitor is connected in series with the start winding of the motor and is controlled by a centrifugal switch, which disconnects the capacitor once the motor …

Series capacitor buck (SC Buck) converters are widely used in voltage regulator modules (VRMs), electric vehicle, photovoltaic (PV) systems, and so on, for the reason that these converters have the characteristics of high step-down ratio and large output current. However, these characteristics can be realized only when the converter …
