　計(jì)算矢量占空比：根據(jù)所選矢量的方向，計(jì)算出兩個(gè)相位信號(hào)的占空比。這個(gè)計(jì)算過(guò)程可以用三角函數(shù)和矢量旋轉(zhuǎn)的方法來(lái)實(shí)現(xiàn)。

　　輸出PWM信號(hào)：根據(jù)計(jì)算得到的占空比，生成PWM信號(hào)，控制電機(jī)輸出。在SVPWM中，PWM信號(hào)的頻率和幅值是固定的，只有占空比在變化。 SVPWM與其他PWM調(diào)制方法相比，具有以下優(yōu)點(diǎn)：

　　低諧波：SVPWM可以產(chǎn)生低諧波的輸出波形，可以減少電機(jī)的振動(dòng)和噪聲。

　　率：SVPWM可以控制電機(jī)的轉(zhuǎn)矩和速度，使電機(jī)運(yùn)行更加。

　　控制：SVPWM可以控制電機(jī)的輸出，可以應(yīng)用于和的電機(jī)控制?？偟膩?lái)說(shuō)，SVPWM是一種的PWM調(diào)制方法，可以將三相交流信號(hào)轉(zhuǎn)換為兩個(gè)相位信號(hào)，從而實(shí)現(xiàn)電機(jī)控制。SVPWM的原理基于空間矢量理論，可以產(chǎn)生低諧波、率的輸出波形。
