Dual Input Dual Output Augmented SPWM based Hybrid Converter for DC Microgrid Application

This paper proposes a high-gain hybrid converter supplying AC and DC loads simultaneously. The proposed converter generates AC voltage by Augmented Sinusoidal Pulse Width Modulation (ASPWM) technique and high gain DC by voltage multiplier cells (VM). This configuration provides integration of renewable sources like solar and battery with variable capacity. A detailed analysis of the proposed converter is presented which includes comparison of number of components, switching statergy, number of renewable and energy storing devices as inputs with other existing hybrid converters and converters. This converter finds application in hybrid microgrids feeding both AC and DC loads simultaneously. The main advantage of the proposed configuration is high density and fewer switches compared with other topologies. This hybrid converter is configured to 1.5kW DC and 320 W AC power. Proposed hybrid converter model is extensively simulated in Matlab simulink.
