Permanent Magnet Generators with Three-Phase Half-Wave Voltage Regulator in Hybrid Vehicles

Permanent magnet generators used in hybrid vehicles primarily provide the equipments in the hybrid cars with the DC power and charge the batteries. The generator rotor is composed of the rotor core and the multi-block Nd-Fe-B permanent magnet fixed on the rotor core. The polar of the adjacent Nd-Fe-B permanent magnet is opposite, in another words, N polarity and S polarity are arrayed alternately. When this rotor rotating, magnetic field rotates with it, the armature coil cuts magnetic-curve, and produces electromotive force. The three-phase half-wave controlled commutation voltage regulator is designed, which can both regulate the voltage and the current and output direct current at the stable voltage. The less power consumption and high-efficiency power generator solve the problems to realize the voltage stability, which generated by the hybrid vehicle´s permanent-magnet generator at wide speed and wide load.
