, 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.The capacitance of the buck capacitor C1 is usually the same as the load current IO: C=14.5*i, where the capacity unit of C is Μf,io unit is a. Example two, according to the buck voltage element selecti

For DC, in the instant of the closed switch, the capacitor is connected to the positive electrode of the power supply, the positive charge is the majority, The negative charge on the plate connected to the anode of the power supply is the majority, and the electric potential of each point in the circuit is equal immediately. Therefore, the capacitor in the DC circuit can play a role in separating the
