Abstract

A three-phase space voltage vector modulated sinewave soft-switching inverter incorporating a single auxiliary resonant snubber into its DC voltage bus line is presented in this paper. This two-level PWM resonant DC link circuit with voltage-clamped PWM and zero voltage holding PWM schemes in DC bus line is described for a soft-switching chopper. The novel soft switching inverter using two-level PWM resonant DC link which includes an optimum type digital voltage servo controller in the d-q coordinate frame is discussed for UPS
