AC Drive Working Principle - Variable Frequency AC Motor How AC Drive Controls Motor Speed As the AC drive provides the frequency and voltage of output necessary to control the speed of an AC motor this is done through PWM VFDs. PWM drives produce pulses of varying widths which are combined to build the required waveform. A diode bridge is used in some converters to reduce harmonics.
