  • Patent number: 11476697
    Abstract: Provided is a battery-charging device that uses a full-bridge rectifier circuit in which each arm is composed of MOSFET as a circuit that rectifies an output of a magnet-type AC generator. The charging device comprises: an ON/OFF state establishment means that, on the basis of a polarity of a potential of each input terminal of the rectifier circuit, establishes ON/OFF state to be assumed by each MOSFET of the rectifier circuit when a battery is charged; a during-charging FET control means that performs control which matches the state of each MOSFET of the rectifier circuit with the state established by the ON/OFF state establishment means when the battery is charged; a short-circuit control means that performs short-circuit control which causes short-circuiting between output terminals of the generator when battery charging is paused; and a FET OFF means that generates a FET OFF time period in which all of the MOSFETs of the rectifier circuit assume an OFF state in a fixed cycle.
