Abstract:
An apparatus includes an inverter configured to be connected to a load, a driver having an output coupled to control terminals of transistors of the inverter and a control input configured to receive control vectors and responsively apply control signals to control terminals of the inverter, a desaturation detector configured to detect desaturation of the transistors, and a controller coupled to the control input of the driver and configured to apply at least one test vector that causes the driver to turn on selected ones of the transistors for a duration sufficient for the desaturation detector to detect desaturation of at least one of the selected transistors and to enable or inhibit further operation of the inverter responsive to the desaturation detector. The load may be a motor and the controller may be configured to apply the at least one test vector responsive to a command to start the motor.

Claim (Index 16):
The method of  claim 11 :\n wherein the inverter comprises a three-level inverter comprising first, second and third legs, each comprising first, second, third and fourth transistors coupled between first and second DC buses, respective ones of the first, second and third legs coupled to respective first, second and third output phases; and wherein the controller applying at least one test vector that causes the driver of the inverter to turn on the selected transistors of the inverter for a test interval having a duration sufficient for the desaturation detector to detect desaturation of the at least one of the selected transistors comprises the controller applying spaced-apart first and second test vectors to the driver that turn on respective first and second groups of the transistors; and wherein enabling or disabling further operation of the inverter responsive to the desaturation detector comprises disabling further operation of the inverter in response to the desaturation detector detecting desaturation of at least one transistor of the first and second groups.
