Study on the IGBT Overcurrent Failure of VSC-HVDC Converter Valve

IGBT overcurrent failure, which is one of the important factors harming VSC-HVDC safe operation, can easily lead to module explosion, water cooling system leakage and even the converter valve shutdown. Based on the structural characteristics and operating conditions of the module multilevel VSC-HVDC...
