Abstract
A generator control unit (GCU) includes a fault detection system configured to generate a direct current (DC) voltage signal based on a difference of a DC-equivalent voltage between the positive and negative exciter gate drive signals. The fault detection system further outputs a fault detection signal indicating the fault status of the gate drive integrated circuits based on a comparison between the DC average voltage signal and a threshold value.
