Abstract Multi-mode modulation strategy is usually used in electric traction drive system. In order to solve the problem of current and torque impact caused by switching between modulation modes, this paper studies the stator flux deviation caused by switching modulation modes, and proposes a general multi-mode modulation switching strategy. By analyzing the influence of changing the switching time on the stator flux linkage in two-phase static coordinate system, the compensation amplitude of each phase switching time is calculated to compensate the stator flux linkage deviation, so as to realize the smooth switching of multi-mode modulation. The strategy compensates the stator flux deviation directly, and it is not constrained by the specific modulation mode and motor parameters, so it can achieve no impact switching at any time. The simulation and experiment verify the generality and effectiveness of the stator flux deviation compensation strategy.

Key words： Multi-mode modulation torque impact switching strategy stator flux deviation switch time correction
