A passive lossless snubber applied to power factor correction boost converter

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A passive lossless snubber is proposed for the power factor correction (PFC) boost converter. By restricting di/dt of the reverse-recovery current and dv/dt of the voltage across the switch, switching loss is significantly reduced. Due to the absence of active components and resistors, the proposed snubber is a good candidate for soft-switching PFC boost converter. The operation principle and steady-state analysis of the proposed converter are provided. A prototype of the proposed snubber circuit is developed, and its experimental results are presented for validation.
