PURPOSE:To reduce load of a battery and a relay circuit by stopping change- over control when an engine is in high rotation in a device in which torque fluctuation due to change-over of electrifying condition is releaved. CONSTITUTION:When an engine rotating number r is larger than a predetermined rotating number (approx 3000rpm), a change-over circuit 27 is connected by a connecting terminal group 25b of a stator coil drive circuit 25. And command signal is output so that a contact 26a of a power generating rotor coil drive circuit 26 is closed. In this case, timing control circuits 37, 38 input it to drive circuits 25, 26 without changing a signal from the change-over circuit 27. Then a solenoid 16 is excited to provide power generating function. 3-phase AC is generated in a stator coil 7 and rectified in a rectifying circuit 30 to charge a battery. In high rotation of the engine, change-over control is stopped and load on a relay circuit can be reduced. |
