Abstract
The controller failure diagnosing device and method may provide a controller failure diagnosing technique that may diagnose a failure in the controller using the characteristics of the controller when using a motor and an inverter. In particular, there may be provided a controller failure diagnosing device and method capable of diagnosing a failure in a controller by comparing the measured 3-phase voltage of the motor and the calculated controller output voltage or by determining entry into an unstable control area condition at an early stage.
