Three-Phase Soft-Switched Quasi Resonant DC Link Inverter for AC Motor Drives with Different Clamps

Abstract

A soft-switched inverter is derived from the passively clamped quasi-resonant link circuit with three different clamps: coupled inductor, diode clamp and coupled inductor and capacitor. The proposed soft-switching inverter is formed from the traditional pulse-width modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft… (More)
