Abstract

The aim of the invention is to maintain voltage supply of an inverter, which is supplied by a supply network, even during a mains power failure. During a mains power failure, the electrical energy required for the voltage supply (2) of the inverter (1) is taken from an output-side throttle (7) of the inverter (1) by means of an auxiliary winding (13).
