Abstract

A novel soft-switching circuit for an AC-DC converter with a four-winding reactor is presented. This AC-DC converter has high efficiency and satisfies the IEC61000-3-2 class D regulation over a wide range of input voltage, for example from 80 to 288 V. The soft-switching circuit reduces the switching power loss and performs power regeneration. As a result, high power efficiency is achieved. The design criteria for the regeneration winding can be further refined for improved performance
