An Integrated Single-stage AC-DC-DC Multiport Converter for Remote Site Applications

A new reduced-switch single-stage AC-DC-DC converter that simplifies the remote site power system architecture interface by integrating several converters together in a single unit is proposed in this paper. The new converter has fewer switches and is simpler to control than prior suggested AC-DC-DC converters of the same type. This paper describes the characteristics of the proposed converter and outlines its operation. Further evidence for the viability of the converter is supplied by simulation as well as experimental results from a scaled-down prototype.
