Two‐Step Commutation Scheme for Isolated Matrix Converters with Reduced H‐Bridge Voltage Spikes and Ringing 

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
ABSTRACT A current‐source converter (CSC)‐derived AC/DC matrix‐type converter is well‐suited for applications requiring a wide range of battery or three‐phase AC voltages. However, the H‐bridge side of the isolated CSC matrix converter suffers from large voltage spikes and ringing.

Experimental Evaluation on the Influence of RCD Snubbers in a 3-Level Thyristor Based MLCR CSC

Journal of Engineering, 2016
Multilevel current reinjection (MLCR) concept provides self-commutation capability to thyristors, enabling thyristor based current source converters (CSC) to operate under negative firing angle. It also lowers the input current harmonic distortion.

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.
