ABSTRACT:
An inverter converting by using semiconductor power switching devices a DC voltage supplied from a main battery to an AC voltage supplied to an AC motor. Unipolar switching devices such as MOSFETs are used as the power switching devices. The power switching devices are controlled so that the output voltage of the inverter is composed of pulses taking three levels in the operation range of high output power. This makes it possible to reduce the stationary loss and switching loss of the switching devices, and to increase the efficiency of the inverter.
