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

Wide Load Range ZVS Three-level DC-DC Converter: Modular Structure, Redundancy Ability, and Reduced Filters Size

Energies, 2019
In future dc distributed power systems, high performance high voltage dc-dc converters with redundancy ability are welcome. However, most existing high voltage dc-dc converters do not have redundancy ability. To solve this problem, a wide load range zero-
