Abstract: A ripple current generation circuit, for use in reducing the loss of a charging switch while achieving discharge energy recovery of an electrolytic capacitor and the low frequency pulsating current charging, and making it possible for the average aging voltage of the electrolytic capacitor to follow the input voltage without being affected by the discharge current. The ripple current generation circuit comprises an input voltage, a switch circuit, an inductor, and a capacitor.
