Quality VFD's incorporate either an AC Reactor or DC Reactor (choke). Their inclusion in the basic design of the VFD allows the design engineer to maximize the advantages of the choke. Their function is to reduce the current distortion caused by the input stage rectifiers by slowing the rate of change of current, and thus charging the internal capacitor at a slower rate over a longer time.
