IET Power Electronics, Volume 18, Issue 1, January/December 2025.This paper designs and implements a fully analogue gate driver for current compensation of paralleled SiC‐MOSFETs. Silicon carbide MOSFETs have current ratings that are not sufficiently high to be used in high‐power converters. It is necessary to connect several MOSFETs in parallel in order to increase current capabilities.

An Isolated SEPIC‐Based AC‐AC Converter for Voltage Sag/Swell Mitigation
IET Power Electronics, Volume 18, Issue 1, January/December 2025.ABSTRACT This paper proposes a high‐frequency isolated buck‐boost AC‐AC converter based on the single‐ended‐primary‐inductance‐converter (SEPIC) topology and its extension circuit with bipolar output. The proposed converters can achieve a wide range of voltage step‐down and step‐up operations with both same‐ and reversed‐phase outputs.
