摘　　要：多块钕铁硼永磁材料由极靴通过非导磁螺钉固定在钕铁硼永磁发电装置转子铁芯上,相邻的钕铁硼永磁材料极性相反,即N极S极间隔排列,组成钕铁硼永磁转子,当转子转动时,磁场旋转,线圈切割磁力线,产生电动势。研发出了三相半控桥式整流稳压器,当钕铁硼永磁发电装置的输出电压低于目标稳压值时,整流稳压器为三相全波桥式整流输出,当钕铁硼永磁发电装置的输出电压高于目标稳压值时,电压信号采样比较电路自动使三相全波整流桥桥臂瞬时断开,降低输出电压,当钕铁硼永磁发电装置的输出电压再低于目标稳压值时,三相全波整流桥再恢复工作,周而复始,整流稳压器通过移相、削波、整流,使输出电压稳定在一定范围内,解决了车辆用永磁发电装置在宽转速、宽负载范围内输出电压保持稳定的问题以及给蓄电池充电的问题。The rotor of Nd-Fe-B permanent-magnet generating set is made up of a rotor core and much of the permanent-magnet material and pole shoes fixed on the core with non-magnetic screw. When the rotor rotates, N poles and S poles alternately pass the stator coils, and it generates electricity. With the developed three-phase half-controlled regulator, the generator will output rectified direct current from the regulator when the rotate speed is low and the output voltage is too low to achieve the target value. With the rise of the rotate speed, the output voltage is higher than the target value. And the comparator＇s voltage of the regulator is high enough to make the trigger turn off the three-phase half-controlled rectifier. The generator＇s voltage drops down quickly after the rectifier shuts off until there is no current through it. Then the output voltage is lower than the target value again, and the rectifier restores to work. Circularly, the generator will output stable direct current and solves the vehicle＇s problem of generating in low speed and the requirement of direct current.
