PCT No. PCT/AU85/00319 Sec. 371 Date Aug. 26, 1986 Sec. 102(e) Date Aug. 26, 1986 PCT Filed Dec. 18, 1985 PCT Pub. No. WO86/03906 PCT Pub. Date Jul. 3, 1986.A regulated chopped DC power supply comprising an alternator with a stator and a rotor, the alternator having a three-phase winding for providing a high voltage output (1, 2, 3) and a star-connected three-phase winding for providing a low voltage output. Also included is a control circuit (14) for controlling a rectifier (12) which is connected to the high voltage output (1, 2, 3) of the alternator to produce a regulated chopped dc output (52) for powering electrical appliances. The control circuit (14) periodically interrupts the rectifier (12) at a frequency to interrupt substantially simultaneously all of the phases of the high voltage output.
