Methods, systems and apparatus for optimization of third harmonic current injection in a multi-phase machine

Patent ·
OSTI ID:1079433

Methods, system and apparatus are provided for increasing voltage utilization in a five-phase vector controlled machine drive system that employs third harmonic current injection to increase torque and power output by a five-phase machine. To do so, a fundamental current angle of a fundamental current vector is optimized for each particular torque-speed of operating point of the five-phase machine.
