The active neutral-point-clamped (ANPC) three-level structure is more advantageous in high-power motor drive systems because it can optimize the loss distribution in switching devices. To improve the performance of a drive system under operation conditions with a low switching frequency, a multi-mode synchronous space vector pulse width modulation (SSVPWM) switching strategy is studied in this paper. Aimed at the problem of current and torque impact caused by the switching between different modes, a multi-mode SSVPWM switching strategy based on pulse insertion is proposed for ANPC three-level inverters. By reconfiguring the stator flux linkage from the motor, the stator flux linkage deviation at the switching position is calculated online, the selection of ANPC redundant zero-state is combined at the switching moment, and the smooth switching between multiple modes is achieved with compensation by inserting the voltage pulse. The correctness and effectiveness of the proposed strategy were verified through simulation and experimental results.
