Abstract

A quasi-resonant DC link converter topology is proposed. The basic topology of the auxiliary quasi-resonant DC link (AQRDCL) is derived from the auxiliary resonant commutated pole (ARCP) converter and is closely related to the active clamped resonant DC link (ACRDCL) circuit. The operation and gating control strategy of the AQRDCL converter, which ensures zero voltage switching of all inverter switches and zero current switching of the auxiliary switches, is presented. The proposed circuit utilizes auxiliary switches to trigger the LC resonance of the DC link to create a zero voltage switching opportunity for the inverter switches. The waveform quality and the performance of the AQRDCL inverter, which has PWM capability, is compared with the DPM strategy of the ACRDCL inverter
