Abstract

A quasi parallel resonant do-link (QPRDCL) circuit with improved PWM capability is Proposed for tile zero voltage switching (ZVS) three phase PWM inverter. The peak voltage stresses of switches are all clamped to the dc-link voltage $V_d$. The proposed QPRDCL inverter has highly improved PWM capability due to selecting the on/off instants of the resonant link at will. Operational principles and analyses of the proposed QPRDCL circuit are explained and verified by simulation results.
