摘要

High voltage inverter (40) has three high voltage switch legs (48,50,52) that are respectively associated with three phase currents. The first leg is modulated at a duty cycle and the second and third legs are clamped to a negative voltage rail if the first phase current is greater than a desired inverter current. The first leg is clamped to a positive voltage rail if the first phase current is less than the desired inverter current. The third leg is clamped to the negative voltage rail and the second leg is modulated at a second duty cycle if the second phase current is greater than zero.
