1·The DC electromotive force output by AC generator can have quite big pulsating voltage.
交流发电机输出的直流电动势会有较大的脉动电压。
2·SVPWM technique have many good qualities, such as less pulsating torque, high usage of DC bus voltage, less switching loss, better high-speed regulation performance.
SVPWM具有较高的直流电压的利用率，开关损耗小，从而实现了高性能的逆变输出。
