Common-Mode Resonance Suppression in Transformerless PWM Current-Source Drive
Abstract
Among high-power pulsewidth modulation (PWM) current-source motor drives, the transformerless structure using the integrated dc choke has been widely acknowledged with superior advantages. A typical challenge faced by such transformerless PWM current-source drive systems is the potential common-mode resonance excited by the common-mode voltage (CMV). Since the implementation of power factor compensation (PFC) at low motor speeds may increase …
