Abstract

PURPOSE: To reduce the size through decrease in the voltage resistance and capacity of AC divided current of the second capacitor by connecting the second capacitor in parallel to a resistance in a series circuit having the first capacitor and thereof connected in parallel between the anode and cathode of the diode.
CONSTITUTION: A second capacitor C2 is connected in parallel to a resistance R in a series circuit having the first capacitor C, and thereof connected in parallel between the anode and cathode of a diode Dd so that the voltage applied on the second capacitor C2 is only confined to the drop in the resistance R. Therefore, in the second capacitor C2, the voltage resistance and capacity of AC divided current less than previously is enough. When the reverse recovered charge within the diode Dd vanishes, the external transient impedance viewed from the diode Dd remains uncharged, thus causing no change in the action of the circuit. With such an arrangement, the diode can operate stably and thus the diode Dd, the resistance R, the first and second capacitors can be packed into the same stack to reduce the size without damage to the reliability.
