Abstract
The utility model relates to a power supply device, in particular to a novel alternating/direct current alternating power supply device. The power supply device comprises a charging circuit and a direct current power supply circuit, wherein the charging power supply circuit is mainly composed of commercial power supply, a resistor, a diode and a storage battery; the fire wire of commercial power supply is connected with the cathode of the storage battery through the diode and the resistor; the anode of the storage battery is connected with the zero wire of the commercial power supply; the direct current power supply circuit comprises the storage battery and user equipment; and transfer switches are connected on the commercial power supply circuit and the direct current power supply circuit. When the instrument is indoors, the instrument is directly connected with the civil alternating current via the power supply device and simultaneously the civil alternating current is used for supplying power to the storage battery. After the instrument is disconnected with the civil alternating current, the transfer switches transfer alternating current power supply to the direct current power supply circuit, and the storage battery with full power supplies power to the instrument via the direct current power supply circuit to meet the requirement that people can use the instrument both indoors and outdoors.
