Abstract :
In this study, a new multi-input converter with two dc inputs and one single phase ac output is proposed, which dc/dc converters are able to operate in buck and boost modes. Both dc/dc and dc/ac part works simultaneously with minimum limitation on the operating function of the other parts. The proposed converter structure and operating principle in all operation modes are presented and discussed. A carrier-based PWM switching method is also proposed for the converter. The proposed converter is simulated and the results are illustrated in the paper. The simulation results verified operation and theoretical analysis of the system.
