Resumen

Multiport DC-DC converters are widely used in hybrid energy generation systems, microgrids and electric vehicles to provide stable power to key loads with high power density. In this project, a multiport isolated bidirectional DC-DC converter is anticipated for hybrid energy storage system in microgrids. Microgrids are connected to the nearby renewable energy generation systems as solar, wind, etc. These systems do not provide pure DC voltage for conversion into AC required by the grid. Hence a single stage DC-AC-DC conversion is required. For energy management and single-stage power conversion, multiport bidirectional converter (BDC) is the best choice. Also to minimize the switching losses and henceforth to improve the efficiency of the converter system, zero voltage switching (ZVS) can be achieved for all switches in any direction of power flow in the whole load range with decoupled duty cycle control and phase shift.   Keywords: DC-bus microgrid, hybrid energy management, hybrid energy storage, multiport bidirectional converterCite This Article Devi RB, Balaganesan SM.
