Isolated DC to Single-Phase AC Converter with Active Power Decoupling Capability Using Coupled Inductor

This paper proposes a novel active power decoupling circuit that is integrated with an interleaved boost converter for isolated DC to single-phase AC conversion applications. The proposed consists of two full-bridge inverters coupled inductor, small buffer capacitor decoupling, and diode rectifier. Further, the controlled independently by coupling inductor common-mode operation converter, respectively. presents control method design criteria passive components. In addition, performance demonstrated experimental results in order confirm validity method. As results, second-order harmonic due double-line frequency ripple reduced 84.5% owing capability. Finally, maximum efficiency 94.5% obtained using converter.
