Single‐Phase Non‐Isolated Interleaved DCM Boost Rectifier With High Power Factor and ZVS Based on TAIPEI Rectifier

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes modifying the Taipei rectifier into a single‐phase version. The rectifier utilizes two boost cells operating in discontinuous‐conduction mode (DCM), separated by a virtual neutral. Frequency modulation (FM) is applied to switch‐on the transistors with zero‐voltage‐switching (ZVS) and maintain a balanced voltage at the output ...

Asynchronous Gating Strategy for Auxiliary‐Free Soft Switching in Parallel‐Active Interleaved Buck Converter

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a novel asynchronous gating strategy to achieve auxiliary‐free Zero‐Voltage and Zero‐Current Switching (ZVS/ZCS) in conventional parallel‐active switch interleaved buck converters. ABSTRACT Conventional interleaved buck converters frequently rely on bulky resonant networks to achieve soft switching.
