<p>An AC to AC converter comprising a multiphase AC power supply (12), a rectifier means (16) connected to the multiphase AC power supply (12) to rectify each of the phases (A, B, C) thereof, a switch means (14) connected to cause the phases (A, B, C) to be switched in and out of circuit, the rectifier means (16) or the switch means (14) having two outputs (20, 22) to which is connected an inverter (24) having an AC output (58, 60) for a load (L) and a control means (70) connected to the inverter (24) to cause switching thereof at a desired frequency to produce a relatively fixed frequency AC supply at the AC output (58, 60).</p> |
