一种新型双模式逆变器驱动的开口绕组永磁同步电机系统及其调制策略

A novel two-mode inverter-based open-winding permanent magnet synchronous motor drive is proposed in this article. The proposed drive operates in hybrid-inverter mode at low and medium speed to achieve high power quality. The common dc-bus mode is adopted at high speed to fulfill a wider speed range than hybrid-inverter mode. Based on the proposed drive, a modulation strategy for any voltage ratio...
