Abstract
Disclosed in the utility model is a switching power supply with the charging function. The switching power supply comprises an input rectification filtering circuit, a transformer, an output rectification filtering circuit and a PWM control circuit, wherein the components are arranged on a PCB board. In addition, a storage battery and a charge-discharge control chip are also arranged on the PCB board, wherein the storage battery and the charge-discharge control chip are respectively connected with a charge-discharge circuit; and the charge-discharge circuit and the charge-discharge control chip are respectively connected with the input terminal of the input rectification filtering circuit. Because the charge-discharge circuit, the storage battery and the charge-discharge control chip are arranged on the PCB board of the switching power supply and the charge-discharge circuit and the charge-discharge control chip are respectively connected with the input terminal of the input rectification filtering circuit, the charge-discharge control chip can control the charge-discharge circuit to charge the storage battery; and when power failure occurs or no current is inputted, the charge-discharge circuit can carry out discharging, thereby ensuring the current output of the switching power supply.

Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The present embodiment provides a kind of Switching Power Supply with charging, and described Switching Power Supply, when there is no electric current input, also can provide electric current output, meets instructions for use.
Wherein, Switching Power Supply comprises input rectifying filter circuit, transformer, output rectifier and filter and pwm control circuit, the electric current of input is undertaken after rectification and filtering by input rectifying filter circuit, transfer in transformer, transformer carries out transformation processing to it, and by exporting after output rectifier and filter rectification and filtering, pwm control circuit one end is connected with the output of output rectifier and filter, the other end is connected with described transformer, by pwm control circuit, carrys out pulse modulation output current.
And, also at the input of described input rectifying filter circuit also, connect a charge-discharge circuit, described charge-discharge circuit is controlled charging and discharging by the connected control chip that discharges and recharges, and, the storage battery being connected with charge-discharge circuit is also set, by storage battery, carrys out storage of electrical energy.
So, when Switching Power Supply does not need input current, can control and discharge and recharge a road accumulators and charge by discharging and recharging control chip, so, when having a power failure, can discharge by discharging and recharging control chip control charge-discharge circuit, meet output current demand.
Or, described in correspondence, discharge and recharge control chip, also arrange one with described in discharge and recharge the charge and discharge switch button that control chip is connected, charge and discharge switch button is fixedly installed on the case surface of Switching Power Supply, by operation charge and discharge switch button, start the work that discharges and recharges control chip, easy to use.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
