Analysis and Design of a Single-Stage ZVS AC- DC Stacked Flyback Converter

Abstract

The analysis and design of a new single-phase single-stage AC-DC converter is the focus of this paper. The proposed converter consists of two lower power flyback converters stacked on top of each other and a single active clamp that helps the main converter switches operate with ZVS. In the paper, the operation of the converter is explained and its analysis and design are examined. Results obtained from an experimental prototype converter are presented to confirm the proposed converter's feasibility.
