WebSince the IGBT turns off very quickly, if the overcurrent is shut off using an ordinary drive signal, the collector-emitter voltage will rise due to the inductive kick, and the IGBT may be destroyed by overvoltage (RBSOA destructions). Therefore, it is recommended that when cutting off the overcurrent WebJun 8, 2024 · An overvoltage is a voltage that surpasses the threshold of mains voltage or the rated voltage of the circuit. As a general rule if the supply voltage increases by 110% of the rated voltage this is then known as an overvoltage. For example, if a device has a specified voltage supply of 230V AC and suddenly is supplied with anything over 250V AC ...
