An Improved Bipolar-Type AC-AC Converter Topology Based on Nondifferential Dual-Buck PWM AC Choppers

A novel single-phase pulsewidth modulation (PWM) direct ac-ac converter based on two-level nondifferential dual-buck ac chopper legs with inverting and noninverting operations is first proposed in this article. It has the ability to resolve both voltage sag and swell problems at the same time when u...
