IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes an improved offline pulse density modulation strategy for the SWISS rectifier to achieve low input current distortion and high power factor at high switching frequencies. Experimental results at 38.4 kHz reduce THDi from over 30% to ≈10%, while high‐frequency simulations at 172.8 kHz achieve THDi of 3.3% and PF = 0.9954.

Gradient Descent‐Based Model Predictive Current Controller for Dual Three‐Phase PMSMs
IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper presents a gradient descent‐based model predictive current controller (TVV‐GD‐MBPCC) for dual three‐phase PMSMs, where the optimal duty cycle and switching state are obtained by minimizing a cost function. Both the proposed and existing controllers are implemented on a TMS320F28379D microcontroller for fair comparison.
