A single to three phase power converter with integrated storage and a PV interface for rural power applications
conference contribution
posted on 2017-12-06, 00:00 authored by Peter WolfsPeter Wolfs, Fuwen YangFuwen YangFor economic reasons, many rural consumers are supplied from single phase medium voltage networks. Three phase power is desirable for many applications. This paper shows that a well-balanced three phase supply can be produced with a Scott transformer connection of a single phase inverter and the existing single phase supply. The single phase converter only processes half of the load power. A regulation scheme based in the DQ frame is proposed and it is shown the single phase inverter directly controls the quadrature axis voltage. A well balanced supply can be produced by regulating this inverter to eliminate any negative sequence voltages. A bidirectional rectifier supplies the inverter and simultaneously provides power factor correction and a reduced cost option to integrate storage and photovoltaic (PV) generation at its DC bus.
