Working principle and calculation of capacitive buck

. three, design examplesFigure 2, the known C1 is 0.33μf, the AC input is 220v/50hz, the circuit can supply the maximum current load. C1 in the circuit of the Tolerance XC is:xc=1/(2πf C) = 1/(2*3.14*50*0.33*10-6) = 9.65Kthe charge current (Ic) flowing through the capacitor C1 is:Ic = U/XC = 220/9.65 = 22mA. (valid value of current)The capacitance of the Buck capacitor C1 is usually approximated by the relationship of the load current IO: c=14.5 I, wh

Phase voltage or line voltage

Phase voltage or line voltage Is the rated voltage in the power system a line voltage or a phase voltage? Only 220 volts is the phase voltage, and others are the line voltage. The voltage between the terminal line and the neutral line is called the phase voltage. The voltage between two ends is called a line voltage. In the power transmission system, there is no Neutral Line on the high voltage line, and only three-phase ABC is sent. Therefore, only
