Traditionally an ac voltage regulator is made with a transformer tap changer or with an acac converter based on buck topologies, recently the developments in ac-ac converter makes feasible the implementation of voltage regulator with other t

A frequency changer or frequency converter is an electronic device that converts alternating current (AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to its
