An Optimised Independent Arm Modulation Strategy Driven by Energy Balance Mechanism for Circulating Current Suppression in Arm‐Multiplexing Modular Multilevel Converters

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
The arm‐multiplexing modular multilevel converter (AM‐MMC) is a lightweight, high‐power‐density topology whose conventional modulation strategies require large circulating currents to maintain energy balance. This paper establishes a time‐domain analytical model of the AM‐MMC energy‐balance mechanism and proposes an optimised independent arm modulation

Multi‐Objective Optimisation Strategy Under Triple Phase‐Shift Modulation for DAB Converter With Extended ZVS Region and Improved Light‐load Efficiency

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Based on triple phase‐shift modulation, this paper proposes an integrated optimisation strategy for dual‐active‐bridge converters that simultaneously minimises both root‐mean square (RMS) and peak currents while significantly extending the zero‐voltage‐switching range.

Method to Maximise Utilisation Rate of Flux Linkage in Coreless Transformer

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
A coreless transformer (CLT) with a maximum utilisation rate of flux linkage is proposed. Compared to existing CLTs, the proposed CLT operates at a significantly lower frequency of 100 kHz, and there is no need for superconductors. Compared with the magnetic‐core transformer (MCT), the proposed CLT has almost the same efficiency, while the gravimetric ...
