This thesis introduces a fault detection and isolation (FDI) method for diagnosis faulty semiconductor switches of a pulsewidth modulated (PWM) voltage source inverter (VSI). This method analyses the pole voltage signals in a time-free domain called voltage space. For a healthy inverter, the project...
