Offline Pulse Distribution Strategies for SWISS Rectifier Using Improved PDM at High Switching Frequencies

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.
