IET Power Electronics, Volume 19, Issue 1, January/December 2026.This study proposes a modular transmitter track design for LCC‐LCC compensated dynamic wireless power transfer systems to mitigate coupling variations during receiver movement. The partially overlapping coils ensure consistent power transfer along different trajectories, with measured current fluctuations below 6.3%.

Research on Full‐Duplex Data Transfer Simultaneously Based on Wireless Power System
IET Power Electronics, Volume 19, Issue 1, January/December 2026.The power transfer of the proposed system uses a bilateral LCC‐type high‐order compensation network. The data injecting circuit (TX1 and TX2) is connected in series to the power circuit through the data coupling transformers Tdt1 and Tdt2, and the data extracting circuit (TR1 and TR2) is connected in parallel to power coils.

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
