Inverter system and method for operating same

An inverter system, comprising:

• a multiphase inverter which comprises at least three half-bridge circuits which are connected in parallel to a positive potential connection and to a negative potential connection;
• wherein all half-bridge circuits each comprise a high-side switch arranged between the positive potential connection and an output of the half-bridge circuit and a low-side switch arranged between the negative potential connection and the output of the half-bridge circuit;
• at least two of the half-bridge circuits comprise a resistive shunt for current measurement which is arranged between the negative potential connection and the output of the half-bridge circuit;
• and
• a control device for actuating the half-bridge circuits, which is configured to actuate the half-bridge circuits for generating voltage space vectors in successive switching periods such that the voltage space vectors are generated by a discontinuous pulse width modulation, in which at least one of the low-side switches of at least of the two half-bridge circuits, which comprise the resistive shunt, is switched to be conductive at least once within a switching period.
