Single Input With Triple Output–Based Boost Converter Including Isolated and Nonisolated Outputs With Reduced Ripples in Source Current

ABSTRACT Nowadays, different configurations of single input with multiple outputs (SIMO)–based boost converters have been reported by researchers because of their high power density. However, the major gap that has been realized in these converters is that the reported converters have either isolated or nonisolated outputs, which limits their application to certain systems only. Keeping this gap in view, the paper presents a single‐input triple‐output boost hybrid interlink converter (SITOBC) that consists of both isolated and nonisolated outputs. To achieve the proposed converter, two dc‐dc boost converters are used. The proposed converter is supplied by a single source and provides one isolated and two nonisolated outputs. The one isolated output is achieved by rectifying the high‐frequency ac voltage getting from the adjacent dc‐dc boost converters, using a fast recovery diodes–based bridge rectifier. The two nonisolated outputs are obtained across the two ends of dc‐dc boost converters. Further, the complementary operation of the switches in the proposed converter results in the reduction of source current ripples. Because of the reduction in ripples of the source current, the losses in the converter decrease, which results in increased efficiency of the converter. Moreover, the comparative study of other state‐of‐art converters with the proposed SITOBC is also carried out. The simulation and experimental results prove the functionality of the proposed converter.
