Abstract

A power supply circuit can be used to provide an alternating-current supply voltage to an electric motor. The power supply circuit is supplied by line power. The power supply circuit includes a inverter including at least one pair of transistor for generating a corresponding phase of the plurality of power supply phases. The inverter includes a transistor control circuit for switching the low-side transistor to its conducting state and the high-side transistor to its non-conducting state in case an excess voltage is detected at the input of the inverter.
