VFD 用于控制交流感应电动机的速度 1它可以通过改变电机供电电压和改变电源频率来实现。VFD 中使用三种主要设计，它们是脉宽调制、电流源逆变器和电压源逆变器

它已成为最常见的驱动控制器，因为VFD 2与电机量程配合使用非常好，它非常可靠，价格实惠，并且仅将最少量的谐波反射回电源。

变频器 1载波频率

VFD is used to control the speed of AC induction motor 1 It can be achieved by changing the motor supply voltage and changing the power supply frequency. There are three main designs used in VFDS, which are pulse width modulation, current source inverter, and voltage source inverter

It has become the most common drive controller because the VFD 2 works so well with the motor range, it is very reliable, affordable, and reflects only a minimal amount of harmonics back to the power supply.
