Abstract
An AC to DC converter comprises a bi-directional switch array converter which converts a three phase AC supply at 50/60 Hz to a high frequency single phase drive for a series resonant parallel loaded tank. The tank is transformer coupled to a rectifier and filter to give a high voltage isolated DC supply to drive a load. The switching of the converter is based on control of the resonant tank to operate as close to a desired tank reference voltage as possible.
