Abstract
Disclosed in the utility model is a switching power supply with the output display 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, the switching power supply also includes an output control chip connected with the output rectification filtering circuit; and a display module connected with the control chip is also fixedly arranged at the surface of a housing of the switching power supply. Because the output chip connected with the output rectification filtering circuit is arranged and the display module connected with the control chip is also fixedly arranged at the surface of the housing of the switching power supply, the output control chip can be used for carrying out processing on the output current to form a display signal and the display module carries out displaying, so that the output current can be checked directly. Therefore, convenient detection can be realized.
Description
Technical field
The utility model relates to Switching Power Supply, a kind of Switching Power Supply with output display relating in particular to.
Background technology

Therefore, there is defect in prior art, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of electric current output display that has, the Switching Power Supply with output display of conveniently checking and detecting.
The technical solution of the utility model is as follows: a kind of Switching Power Supply with output display, comprise the input rectifying filter circuit, transformer, output rectifier and filter and the pwm control circuit that are arranged on pcb board, also comprise the output control chip being connected with described output rectifier and filter; Described output control chip is arranged on described pcb board, and the case surface of Switching Power Supply is also fixedly installed the display module being connected with described control chip.
Be applied to technique scheme, in described Switching Power Supply, between described output control chip and described input rectifying filter circuit, the first testing circuit be set, between described output control chip and described output rectifier and filter, the second testing circuit is set.
Adopt such scheme, the utility model is by arranging the output control chip being connected with output rectifier and filter; And be also fixedly installed in the case surface of Switching Power Supply the display module being connected with control chip, so, can output current be processed and form display by output control chip, and show on display module, can directly check output current, convenient detection.
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 output display, and described Switching Power Supply has output display, can see intuitively output current situation, and controls output current numerical value, checks conveniently.
As shown in Figure 1, Switching Power Supply comprises input rectifying filter circuit, transformer, output rectifier and filter and the pwm control circuit being arranged on pcb board, 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, one output control chip is also set, output control chip is fixed on pcb board, described output control chip is connected with described output rectifier and filter, electric current is after the rectification of output rectification filter device and filtering, after described output control chip, export, so, can control by output control chip the size of its output current, and, by described output control chip according to output current, process and form display, and control connected display module and show, wherein, display module is fixedly installed on the surface of Switching Power Supply, conveniently check.
And, also between described output control chip and described input rectifying filter circuit, the first testing circuit is set, and between described output control chip and described output rectifier and filter, the second testing circuit is set.The first testing circuit detects the input and output current conditions of described input rectifying filter circuit, the second testing circuit detects the input and output current conditions of described output rectifier and filter, and feed back in output control chip, can also process by output control chip, and by display module, show the current conditions of each circuit, show more comprehensively, view result is better.
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.
