| Abstract |
This paper proposes the fault-tolerant control of a series connectable modular full-bridge inverter in case of an open switch fault. The faulty main switch is detected and identified by comparing the value of the measured phase node output voltage with the PWM signal generated for the respective phase leg. The series switch fault is detected and identified by comparing the measured output voltage of the phase legs connected by the series switch with a reference value. The post-fault control following an open main/series switch fault is realized by modifying several reference values in the healthy control system and is validated for several fault scenarios. |
