A Passive Variable Switching Frequency PWM for Three‐Phase Three‐Level T‐type Converter With Reduced Harmonic and Low Switching Loss
To address the issues of concentrated harmonic energy and high electromagnetic interference (EMI) peaks in T‐type neutral‐point‐clamped converters(T‐NPC) under the traditional constant switching frequency pulse width modulation (CSFSPWM), this paper proposes a passive variable switching frequency pulse width modulati...
