Four-phase half-wave controlled bridge rectification regulator permanent-magnet generator with vacuum pump for vehicles

The regulated permanent-magnet generator with vacuum pump is mainly used to provide direct current for vehicle's electrical equipment, recharge the storage battery and provide vacuum booster of energy for the brake system. The permanent-magnet generator rotor is fixed to the rotor iron core by many blocks of permanent-magnet material through pole-boots and non-magnetic screws, and the adjoining permanent-magnet material's polarity is opposite, that is N polarity and S polarity are arrayed alternately, which compose the permanent-magnet rotor. When rotor is rotating, magnetic field rotates with it, meanwhile, armature coil cuts magnetic-curve and produces electromotive force. The four-phase half-wave controlled bridge rectification voltage regulator is designed, which can regulate both the voltage and the current,so the problem of instable voltage, which is generated by the automobile's permanent-magnet generator at wide speed and wide load, is solved.
