Abstract
A passive coupled-inductor soft-switching circuit of a power factor corrector is provided. The passive coupled-inductor soft-switching circuit includes a power input terminal, a first inductor, a first diode, a power output terminal, a power switch and a buffer circuit. The first inductor has a first terminal and a second terminal, wherein the first terminal of the first inductor is electrically coupled with the power input terminal. The first diode has a positive terminal and a negative terminal, wherein the positive terminal of the first diode is electrically coupled with the second terminal of the first inductor. The power output terminal is electrically coupled with the negative terminal of the first diode. The buffer circuit is electrically coupled with the power switch. By using the buffer circuit, the voltage and current have phase interlacing shifts and thereby reducing the switching loss.
