Abstract
A configuration for starting an inverter includes a capacitor which is provided for overvoltage protection in a half-controlled 3-phase bridge, with a discharging resistor used for charging an intermediate-circuit capacitor through a switch and a diode, in such a manner that an isolating transformer at the output of an inverter is premagnetized so that the inverter reliably turns on during the starting process.
