IET Electric Power Applications, Volume 18, Issue 5, Page 527-542, May 2024.A programmed hybrid spreading spectrum modulation method to mitigate electromagnetic interference (EMI) emission in the context of miniaturised and lightweight synchronous machine drives is proposed. The proposed method is well‐suited for controlling synchronous motors using three‐phase two‐level voltage source inverters.

New single‐stage bidirectional three‐phase ac‐dc solid‐state transformer
Electronics Letters, Volume 60, Issue 2, January 2024.This letter extends a new isolated bidirectional three‐phase buck‐boost power‐factor‐correction rectifier concept to medium‐voltage input, resulting in an solid‐state transformer (SST) that performs MVac‐LVdc conversion in a single converter stage and, unlike many modular SST concepts, employs only a single medium‐frequency transformer.

IET Electric Power Applications, Volume 18, Issue 1, Page 128-140, January 2024.Based on space voltage vector, a voltage vector combination was derived to minimise the capacitor current within a single switching cycle. Compared to the traditional SVPWM, experimental results have shown that the rms value of capacitor current can be reduced by up to 37%.
