Abstract
Systems and methods for controlling one or more inverters in response to detecting a desaturation (DESAT) fault are disclosed herein. A DESAT fault of an inverter coupled to a motor is detected. In response to detecting the DESAT fault, all driving switches of the inverter are instructed to open. The driving switch that failed and a type of failure are determined based on current of the motor during a predetermined time period after instructing all of the driving switches to open, and the remaining driving switches are controlled based on which switch failed and the type of failure.
