PLC系统模块EL9010
计算矢量占空比：根据所选矢量的方向，计算出两个相位信号的占空比。这个计算过程可以用三角函数和矢量旋转的方法来实现。
输出PWM信号：根据计算得到的占空比，生成PWM信号，控制电机输出。在SVPWM中，PWM信号的频率和幅值是固定的，只有占空比在变化。 SVPWM与其他PWM调制方法相比，具有以下优点：
低谐波：SVPWM可以产生低谐波的输出波形，可以减少电机的振动和噪声。
率：SVPWM可以控制电机的转矩和速度，使电机运行更加。
控制：SVPWM可以控制电机的输出，可以应用于和的电机控制。总的来说，SVPWM是一种的PWM调制方法，可以将三相交流信号转换为两个相位信号，从而实现电机控制。SVPWM的原理基于空间矢量理论，可以产生低谐波、率的输出波形。
