Webseveral methods, to simultaneously change the voltage and frequency to maintain the constant volts/hertz ratio throughout the 0 - 60 Hz range. On most AC variable speed drives the voltage is held constant above the 60 hertz frequency. The diagram below illustrates this voltage/frequency relationship. WebA VFD (or Variable Frequency Drive) achieves this by converting the AC power to DC. The VFD then sends out a DC pulse that acts as an AC sine wave to control intensity. Operators can select the desired output frequency to control the speed of the motor. There are two main types of VFDs. Voltage/Hertz VFDs are the most common and cost-effective.
