Zusammenfassung:	The method connecting direct-voltage input to a power supply grid via an alternating-voltage output. The inverter is involved in a power flow interaction with the grid in such a manner that leakage current (IA) occurs during operation of the inverter, and the leakage current is controlled in the operational control of the inverter by changing a set value for an intermediate circuit voltage (UZwK) of an intermediate circuit of an inverter. A pulse width modulation technique is used for controlling an output of the inverter module for operation control of the inverter.
