    摘要: When charging a battery of a low-voltage system, a battery charging apparatus of the present invention switches on a field-effect transistor and distributes the output of a generator via a diode to the battery. Further, when charging a battery of a high-voltage system, the battery charging apparatus switches off the field-effect transistor and distributes the output of the generator via the diode to the battery. At this time, the field-effect transistor is switched, and chops the output of the generator. Then, by selecting the duty of a clock signal for controlling this switching, the output powers of the generator when charging the high-voltage system and when charging the low-voltage system are made substantially equal, reducing fluctuation in the input torque of the generator.
