Abstract
Official abstract text for this publication.
A power factor correction circuit may include a boost converter circuit in which a plurality of boost circuits including a boost inductor, a rectifying diode, and a boost switch are connected with each other; and a snubber circuit including a snubber inductor and a snubber switch so as to snubber the boost converter circuit. The snubber inductor may be controlled so as to be turned on before the boost inductor is turned on to apply zero voltage to the boost inductor. It is possible to reduce switching loss occurring when the boost switch is turned on and increase efficiency of an AC-DC power supply apparatus.
First claim
Opening claim text (preview).
What is claimed is: 1. A power factor correction circuit, comprising: a boost converter circuit in which N boost circuits including a boost inductor, a rectifying diode, and a boost switch are connected with each other; and a snubber circuit including N snubber switches and M snubber inductors so as to snubber the boost converter circuit, wherein N and M meet N>M, and at least two of the N snubber switches are directly connected with one snubber inductor to share a snubber ind…
