DEVICE FOR CONTROLLING CHARGING GENERATOR FOR VEHICLES

摘要

PROBLEM TO BE SOLVED: To achieve a more inexpensive device for controlling a charging generator for vehicles, easy to correspond with both machine models using and not using a pressure rising circuit to reduce costs by the effect of mass production.

SOLUTION: The device for controlling the charging generator for vehicles has: a field coil wire 13 rotated by an engine to make a rotating magnetic field; an armature coil wire 11 that generates a current by the rotating magnetic field of the field coil wire 13 to charge a battery 16 via a rectifier 12; a voltage controlling IC regulator 14 that adjusts the voltage of the battery 16; an n-channel power MOS transistor used as a high-side switch; and a pressure rising circuit that generates the gate voltage for controlling the n-channel power MOS transistor so as to drive the pressure rising circuit when voltage supply to the drain terminal of the n-channel power MOS transistor is detected.
