Abstract:
The invention relates to an inverter circuit (80) which comprises first and second switching means (1, 2) that are connected, in an electrical path (10), in series to one another and parallel to a DC link capacitor (20). Said inverter circuit (80) also comprises an output (9) and two inputs (11, 12) which are each electrically-conductively connected to a pole of the DC link capacitor (20) and can each be connected to a pole of an energy store. Said inverter circuit (80) also comprises a voltage limitation element (30) which is electrically-conductively connected to the electrical path (10) by a first connection between the two switching means (1, 2), and to the control connection (3) of the second switching means (2) by a second connection. According to the invention, a capacitor (40) is arranged in said electrically-conductive connection between the voltage limitation element (30) and the control connection (3) of the second switching means (2), and a reference voltage source (50) is electrically-conductively connected to the first connection of said voltage limitation element (30).
