What is an AC Drive?

An AC drive is a device that is used to control the speed of an electrical motor, either an induction motor or a synchronous motor. AC drives are also known by various other names such as adjustable speed drives (ASD) or adjustable frequency drives (AFD) or variable frequency drives (VFD) or variable speed drives (VSD) or frequency converters (FC).
