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.

Abstract: A discharge circuit for a diode reverse leakage current includes an input positive terminal, an input negative terminal, an output positive terminal coupled to the input positive terminal, an output negative terminal coupled to the input negative terminal, a diode and a current source device. The diode has an anode terminal coupled to the input positive terminal and a cathode terminal coupled to the output positive terminal. The current source device has a first end coupled to the anode terminal of the diode and a second end coupled between the input and output negative terminals. The voltage difference across the current source device is reduced by less than about 1 V when input voltage is switched off. The current source device continues to operate when the input voltage is normal. As P=VI, the loss is proportional to the input voltage, therefore achieving the objective of low loss.
