Abstract
This paper investigates two diagnosis methods based on switching voltage pattern for IGBTs open-circuit faults in voltage-source inverters. One is based on bridge arm pole voltage, and the other is based on bridge arm line voltage. With extra simple circuit, these two diagnosis methods can detect and identify single and multiple open-circuit faults of the inverter IGBTs effectively. The comparison of diagnosis time and anti-interference feature between these two methods has been presented. The simulation results are carried out to show the effectiveness and differences of these two methods.
