Description
Technical field
The utility model relates to switch power technology field, specifically a kind of high power switching power supply based on DSP.
Background technology
High power switching power supply is exactly conducting with being undertaken by circuit controling switch pipe at a high speed and cut-off, is that high-frequency alternating current is supplied to transformer and carries out transformation by DC conversion, thus one or more groups voltage required for producing.Along with the high speed development of power electronic technology, the work of power electronic equipment and people, the relation of life are day by day close, and electronic equipment all be unable to do without reliable power supply, various electronics, electric equipment field, stored-program control exchange, communication, electron detection device power supply, control appliance power supply etc. employ Switching Power Supply all widely, more facilitate developing rapidly of switch power technology.But the problem that high power switching power supply existence and stability is poor, poor reliability, automaticity are low at present, can not meet the work requirements of more low-voltage, high-current field of operation.
Utility model content
Not enough for above-mentioned prior art, the utility model provide a kind of stable and reliable operation the high power switching power supply based on DSP.
A kind of high power switching power supply based on DSP that the utility model provides is achieved through the following technical solutions:
A kind of high power switching power supply based on DSP, it is characterized in that: comprise filter, input rectifying filtration module, high-frequency inversion module, high frequency transformer, output rectification filter module, dsp controller, protective circuit module, sample circuit module, drive circuit module, described filter input end connects ac input end, described filter output connects described input rectifying filtration module input, described input rectifying filtration module output connects high-frequency inversion module input, described high-frequency inversion module output connects high frequency transformer input, described high frequency transformer output connects output rectification filter module input, described protective circuit module is serially connected between ac input end and DC output end, and be connected with dsp controller, described dsp controller connects sample circuit module and drive circuit module, described drive circuit module connects high-frequency inversion module, for controlling high-frequency inversion module, the described sample circuit module other end connects DC output end.
The beneficial effects of the utility model are:
1, dsp controller is a kind of high performance controller with Digital Signal Processing speciality, can carry out many-side control Switching Power Supply, more intelligent;
2, device simplifies more, effectively reduces the volume and weight of device, reduces cost, decrease power consumption, improves the reliability of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
A kind of high power switching power supply based on DSP as shown in Figure 1, it is characterized in that: comprise filter, input rectifying filtration module, high-frequency inversion module, high frequency transformer, output rectification filter module, dsp controller, protective circuit module, sample circuit module, drive circuit module, described filter input end connects ac input end, described filter output connects described input rectifying filtration module input, described input rectifying filtration module output connects high-frequency inversion module input, described high-frequency inversion module output connects high frequency transformer input, described high frequency transformer output connects output rectification filter module input, described protective circuit module is serially connected between ac input end and DC output end, and be connected with dsp controller, described dsp controller connects sample circuit module and drive circuit module, described drive circuit module connects high-frequency inversion module, for controlling high-frequency inversion module, the described sample circuit module other end connects DC output end.
In the utility model, ac input end voltage obtains direct voltage after filter carries out filtering and input rectifying filtration module carries out rectifying and wave-filtering, by high-frequency inversion module, DC voltage conversion is become high-frequency ac voltage, again through high frequency transformer isolated variable, high-frequency ac voltage needed for output, eventually pass output rectification filter module, after the high-frequency ac voltage rectifying and wave-filtering that high frequency transformer is exported, is obtained required direct voltage; Sample circuit module for gathering the direct voltage information of output, and feeds back to dsp controller, is controlled the voltage transformation parameter of high-frequency inversion module, thus obtain reliable and stable direct voltage by dsp controller.
The above embodiment only represents execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to the utility model protection range.
