具有隔离直流源的开口绕组永磁同步电机多模式载波PWM策略

A multimode carrier-based PWM strategy for open-end winding permanent-magnet synchronous motor (OW-PMSM) with isolated dc sources is proposed in this article. For the proposed strategy, the independent reference voltages of both the two inverters are obtained by decomposing the reference voltage output from the controller. Then, multiple modulation modes are established by different combinations o...
