Research on SIDO Converter and Its Power Decoupling Control Strategy

Abstract

Different voltage levels are needed in the wide application of microgrids and distributed energy. To meet demand, this paper proposes an integrated single-input dual-output (SIDO) ac-dc converter with a component count reduction, providing two different dc voltage levels. Based on the comprehensive analysis of the topology, power factor correction (PFC) control strategy and the power decoupling control strategy for different voltage levels are designed. Furthermore, the experimental results based on a prototype circuit are demonstrated to validate the theoretical analysis.
