Method for operating an electric circuit

The method involves detecting fault of an electrical circuit (10), and measuring signals within the circuit. A target condition is determined in event of fault depending on the measured signals, where the circuit for control of the fault is transferred in the target condition. A sequence is determin...

Summary:The method involves detecting fault of an electrical circuit (10), and measuring signals within the circuit. A target condition is determined in event of fault depending on the measured signals, where the circuit for control of the fault is transferred in the target condition. A sequence is determined depending on the measured signals, and switching devices e.g. insulated gate bipolar transistors (121-124), of an inverter e.g. three point neutral point clamped (NPC) inverter (11), are transferred into a target switching condition corresponding to the target condition with the sequence.
