  • Battery charger having current increasing circuit
    Patent number: 6184657
    Abstract: A battery charger is adapted to increase a charge current applied to at least one battery from a predetermined supply voltage. The charger includes a supply voltage generating device coupled to an AC voltage source for generating the predetermined supply voltage and a charging circuit electrically connected to the supply voltage generating device. The charging circuit includes a first capacitor and a second capacitor AC coupled to the first capacitor. The charging circuit is adapted to apply the charge current from the supply voltage generating device to the at least one battery through the first capacitor during a first half of a charging cycle, and store the charge current from the supply voltage generating device in the second capacitor during a second half of the charging cycle.
