ABSTRACT:
Due to the intermittent nature of electrical connection through moving contacts on electrically propelled vehicles, electrical power converters such as power supplies and inverters are subject to large voltage transients. For compactness and low weight, a high-frequency power converter comprised series-connected high-speed switching circuits, so that an input voltage with voltage transients is split between the switching circuits. As a result, lower-rated switching elements such as IGBT's and MOSFET's can be used while maintaining resistance to input-voltage transients.
