New description: [New technical field] This is a power converter, especially a power converter with backup power supply. [Prior Art] Due to the development of electronic technology, most of the small household appliances and 丨τ information products contain digital circuit design. A large proportion of these products must be supplied with DC power supply. Such a small household appliance and IT information product using a DC working power supply, as shown in the sixth figure, usually comes with a power converter (7 〇) (Adapter), which is a module. The outer portion is provided with a pair of connecting wires (7 1 ) and a DC power supply line (7 2 ) for plugging into the parent flow mains socket for AC power, and internally There is an AC/DC power conversion circuit (not shown), which converts the parent current power into DC power and sends it out by the DC power line (7 2 ). The DC power cable (7 2 ) can be connected to the direct current power jack of small appliances and |T information products, and the power converter (70) can supply power to small appliances and 丨τ - information products. This power converter (70) converts AC power to DC, making it easy to use small appliances and IT information products. However, these power converters (7 ◦) can only passively perform the AC/DC conversion of the power supply. Once the AC power is interrupted (blackout), the power converter (7 〇) is useless. In addition, if small appliances and Kenting information products are completely out of power, small appliances can't rely on the power converter (7 〇) to supply power, and the M324919 continues to use, causing great inconvenience and trouble. [New content] As can be seen from the above, at present, small household appliances and Kenting information products generally use power converters to obtain working power, but power converters can only passively convert power supplies. Once power failures are in demand for power consumption of load devices, there is no Any positive activity with built-in and constructiveness causes users to be troubled and inconvenient in using electricity. Therefore, the main purpose of this creation is to provide a power supply converter with a power supply function, which can convert AC power to DC power under normal conditions to supply power for the load device. Once the AC power supply is interrupted, the power converter has a power storage function. It can be used as a backup power supply, so that the load equipment can be used continuously. The main technical means adopted to achieve the foregoing objectives is that the power converter includes: a module body, the outer portion of which is provided with a pair of power strips and a DC power output interface, the former is for plugging the power socket to obtain AC power, and the latter is An AC/DC converter is provided in the module body, and has an input end and an output end. The input end is connected to the power receiving piece for using the foregoing The AC power is converted into a DC power source, and the output end forms a DC power supply circuit with the DC power output interface to transmit a DC power supply; and an power storage unit is connected to the DC power supply circuit of the AC/DC converter. In order to be converted by the AC/DC converter, the DC 4 M324919 source is charged; in the normal condition of the AC power supply, the DC power generated by the AC/DC converter conversion is directly supplied to the load device. At the same time, charge the internal power storage unit until it is fully charged. As a result, when the AC power supply When disconnected, the power converter can send the power stored in the power storage unit to the DC power supply circuit to supply the backup power, so that the load device can continue to work, effectively avoiding the trouble caused by power failure. A DC/DC converter is further connected in series with the power supply circuit, and the DC/DC power conversion circuit is disposed between the power storage unit and the DC power output interface for outputting the DC power of the AC/DC converter or the power storage unit. A DC power source that is converted into a specific voltage. A DC/DC converter is provided between the power storage unit and the DC power supply circuit to convert the DC power output from the power storage unit into a DC power supply of a specific voltage. The power output interface is connected in series with the switch, and the switch is turned on or off to determine whether the power is supplied. A switch is connected between the power storage unit and the ground terminal, and whether the power storage unit is working (charging/power supply) is determined by whether the switch is turned on or not. The power storage unit is a battery. The DC/DC converter is one liter. The DC/DC converter is a step-down converter. The DC/DC converter is a step-up/step-down converter. 5 M324919 [Embodiment] Please refer to the figure in the figure - The circuit diagram of the first preferred embodiment of the present invention is mainly for the module body (i outer part Μ __ Μ (1 1) and the direct current power output interface (丄2), the power receiving piece 〇 1) is inserted Connect to the power socket to obtain AC power.
