摘要： 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 (0 &cir& /1, 0 &cir& /2, 0 &cir& /3) and a star-connected three-phase winding for providing a low voltage output. Control means (14) for commutating rectifier means (12) connected to the high voltage output (0 &cir& /1, 0 &cir& /2, 0 &cir& /3) of the alternator to produce a regulated chopped dc output (52) for powering electrical appliances. Regulating means (15) for regulating rectified low voltage output (B ) of the low voltage winding of the alternator. The regulating means (15) being operable in two modes, a car mode in which the rectified low voltage output (B ) is connected to a battery (124) for charging said battery and energising the alternator excitation winding (134) at battery voltage, and in a power mode in which the battery (124) is disconnected from the rectified low voltage output (B ), and the excitation winding (134) is energised from the star point (N) of the low voltage winding of the alternator, this excitation being used to boost the power output (B ) for use in welding, etc.
