Abstract
The disclosure is a method for operating an inverter with a DC input and an AC output. The DC input is connected to a DC source, bridge branches of a bridge circuit are connected to the AC output via power chokes, and the AC output is connected to an AC grid via isolating switches. The method includes opening the isolating switches, and controlling semiconductor switches of at least two bridge branches of the bridge circuit that are connected downstream of at least one power choke at the AC side, such that a DC source connected to the DC input is loaded. The sum of the currents flowing out of at least one of the at least two bridge branches on the AC side corresponds to the sum of the currents flowing into at least one other bridge branch of the at least two bridge branches on the AC side.
