Patent ID: 7659679

Claim:
A method for adjusting a dead-time interval between de-activating a first transistor and activating a second transistor in a motor control circuit, the first and second transistors being electrically coupled in series with one another, the method comprising: determining a plurality of commanded torque values associated with a motor based on a received signal over time, each commanded torque value of the plurality of commanded torque values being indicative of a commanded torque level of the motor; setting the dead-time interval value equal to a first value when one commanded torque value of the plurality of commanded torque values is within a first torque range; decreasing the dead-time interval value as other commanded torque values of the plurality of commanded torque values increase over time within a second torque range, the second torque range being greater than the first torque range; and wherein the dead-time interval value is indicative of a desired dead-time interval.
