System and method for adjusting a dead-time interval in a motor control circuit |
摘要 |
A system and a method for adjusting a dead-time interval between de-activating a first transistor and activating a second transistor in a motor control circuit are provided. The method includes determining a plurality of commanded torque values associated with a motor based on a received signal over time. The method further includes 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. The method further includes 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 is greater than the first torque range. The dead-time interval value is indicative of a desired dead-time interval.
