Embodiment Construction
[0017] In the embodiment: R1, R2, R3, R4, R5, R6, R7, R8 are resistors; D1, D2, D3, D4, D5, D6 are high-power rectifier tubes; D7 is a low-power diode; T1 is a Darlington T2, T3, T4 are triodes; C1, C2 are electrolytic capacitors; S1 is a power tube, which can be a turn-off thyristor, a power transistor, a field effect tube or an insulated gate bipolar transistor; Dw1, Dw2 Is the Zener diode; F is the excitation winding; JF1, JF2, JF3 are the three-phase armature windings of the alternator.
[0018] The present invention will be further described below in conjunction with accompanying drawing:
[0019] figure 1 Provide a car alternator controller that can provide 42V and 14V power at the same time. The 42V voltage positive output terminal is at the upper right of the figure, the 14V voltage positive output terminal is at the upper left of the figure, and the negative poles of both are grounded. The first phase winding JF1, the second phase winding JF2 and the third phase win...
