Abstract:In the renewable power system with two or more sources, the application of multiple-input converter (MIC) instead of several single-input converters can simplify the circuit and reduce the cost. A novel multiple-input full bridge converter is proposed in this paper. Taking the two inputs as the example, the operation modes and the characteristics of the double-input full bridge converter are presented. By applying the proposed multiple phase-shift control strategy, the soft-switching technology is accessible. Power management method of the new converter is also introduced. Finally, an 800W prototype is built to verify the theoretical analysis and the effectiveness of the control strategy.
