Abstract
A five-voltage level inverter topology circuit and a three-phase five-voltage level inverter topology circuit, suitable for use with two series-connected direct current (DC) power sources, include a half-bridge inverter circuit having a first circuit module and a second circuit module. The half-bridge inverter circuit outputs five voltage levels including a 0V level. The five-voltage level inverter topology circuit has a five-voltage level half-bridge structure, and only requires an alternating current (AC) filtering inductor, thereby reducing system cost and size, removing leakage current, and providing high efficiency.
