摘要

The injection of a third harmonic current can improve the electromagnetic torque output of the five-phase permanent magnet synchronous motor. In this paper, constant copper consumption and constant maximum current are used as constraints, and the influence of the ratio between the third harmonic current and the fundamental current on the electromagnetic torque under the two constraints is analyzed. The electromagnetic torque is the largest when the third harmonic current reference value is equal to the fundamental current reference value of ψf3f times under the premise of the constant copper loss. On the premise that the maximum current is constant, the electromagnetic torque is the largest when the third harmonic current reference value is equal to the fundamental current reference value of kw/(6kw-kw3/3) times. On this basis, according to the vector amplitude, phase and action time, the changing trends of maximum voltage utilization rate with Vref3/Vref1 under three different kinds of methods are given. Finally, through the experimental platform, the control effects of the three kinds of SVPWM are compared under two constraint conditions.
