Development of a Medium Voltage, High Power, High Frequency Four-Port Solid State Transformer

The power and voltage levels of renewable energy resources is growing with the evolution electronics switching module technologies. For that, need for development a compact highly efficient solid-state transformer becoming critical task in-order to integrate current AC grid new systems. objective this paper present design, implementation, testing multi-port microgrid integration applications. proposed system has four-port four converters connected ports. windings integrated on single common core. Thus, it can different storage Each port rated 25kW, frequency pushed 50kHz. ports are chosen represent realistic industrial model consisting grid, system, photovoltaic load. designed operate at 4.16kVAC corresponding 7.2kV DC bus voltage, while other three 500VDC. Moreover, active dual bridge topologies, load passive full rectifier one. design first validated simulation results, then implemented tested. Experimental results show that suitable medium integration.
