Technical Examples
  1. An inverter fault detection system of the present invention is provided with: bus voltage monitor means for monitoring the bus voltage of a three-phase inverter; output voltage monitor means for summing the phase output voltages coming from the three-phase PWM inverter, and for outputting the resulting summed output voltage through a filter having a low-pass characteristic of passing through only the cutoff frequency lower than the PWM carrier frequency; and fault determination means for determining that the three-phase PWM inverter is in the faulty state when the output voltage coming from the output voltage monitor means is almost the same as the voltage value corresponding to 3/2 times of the bus voltage monitored by the bus voltage monitor means.
