Hybrid Pulse-Width Modulation Strategy With Reduced High-Frequency Common-Mode Voltage to Lower RMS Motor Leakage Current for a Three-Level Neutral Point Clamped Converter

open access: yesIEEE Access, 2023
Due to the capacitive nature of Common-mode impedance, high-frequency Common-mode voltage due to high switching frequency leads to an increase in RMS leakage current, which, in turn, causes higher power loss, Electromagnetic Interferences, and ...
