Abstract

See full text

A charger device includes a switch, a rectification circuit, a DC/DC converter, and an automatic disconnecting circuit. The automatic disconnecting circuit is connected to the switch, the battery, the rectification circuit, and the DC/DC converter. The automatic disconnecting circuit automatically disconnects the charger device from the alternating current power source when the battery is fully charged. The automatic disconnecting circuit includes an inductor, a first resistor, a capacitor, a second resistor, a third resistor, a comparator, a switch element and a relay. The relay comprises a coil and a normally-open switch. The normally-open switch turns on or off according to the switch element to control a connection between the charger device and the alternating current power source.
