PROBLEM TO BE SOLVED: To realize well-balanced charging of a battery by rectifying a current using a first switching circuit, including a circuit for outputting a current to a battery or a capacitor using the second or third witching circuit and driving the first switching circuit to use a magnetic type generator as a motor. SOLUTION: When a three-phase magnet-type generator used concurrently as a generator, an AC is applied when power generation output is generated in u, v, w phases with the rotation of an engine. The output of the generator smoothed with the first switching circuit is generated and makes conductive the second and third switching circuits, depending on the battery voltage lower than the specified voltage to charge the battery. When the battery voltage is higher than the specified voltage, these circuits are not conductive, and thereby the battery is not charged to control the battery voltage to a constant voltage. Thereby, different voltages can be obtained under a well-balanced condition, and the battery can be charged from a low voltage to a high voltage. |
