  • Abstract
    This paper proposes a quasi-square-wave DC link (QSWDCL) converter, which improves the performance of an existing topology. The proposed circuit provides zero-DC-link voltage notches, during which the inverter switching is effected, and imposes a minimum DC bus voltage stress to the PWM inverter. Simple design conditions are offered. Simulated and experimental results demonstrate the validity of the proposed topologies.
