Beschreibung
Zusammenfassung:	A power conversion apparatus employs multi-level techniques and wide band-gap semiconductor switching devices to achieve high efficiency in a converter system having high power density. The apparatus may be configured as a bi-directional conversion system capable of operating as both an inverter, configured to receive DC power and produce AC power, and as a rectifier configured to receive AC power and produce DC power. The apparatus is especially suitable for electric vehicle (EV) applications.
