Electrical power is supplied to an electric vehicle rapid DC charging station requiring a multi-phase electrical input, by converting single phase utility power using high-capacity converters of various designs. In certain embodiments, a low-capacity converter may also be coupled to single-phase utility power input for provision of power to the charging station when no vehicle is present for charging. In these embodiments, a transfer switch selectively couples the high-capacity converter or low-capacity converter to the rapid charging station as needed to charge an electric vehicle. Other embodiments may also include energy storage devices for enhancing charge rates or providing charging during periods of inadequate power availability or poor utility power quality.
