It is directly related to the even running of electrical network.
Utility model content
Background technology is based on, the utility model proposes a kind of high frequency switching rectifier module, which has stable rectification output,
And with the function of coordinating external module or equipment to realize Based Intelligent Control, its particular technique content is as follows：
A kind of high frequency switching rectifier module, with input and outfan, which includes being sequentially connected to the input and defeated
EMI lightning-protection modules, full-bridge rectification module, passive PFC module, DC-DC conversion modules and the filtration module gone out between end, the DC-
DC conversion modules are controlled by a control module, and the control module is connected to the outfan of filtration module by a sampling module, should
Control module is provided with the function port that several are connected with external module.
In the middle of one or more embodiments of the present utility model, the function port of the control module includes that stream signal is defeated
Inbound port, excess temperature signal input port, and overvoltage excessively stream short-circuit signal input port.
In the middle of one or more embodiments of the present utility model, the control module is provided with to external module or equipment to be fed back
The FPDP of data.
Compared with prior art, its advantageous exists this utility model：First, the EMI lightning protection for being provided with input side is protected
Shield, with the situation that tackles line voltage fusion and form instantaneous overvoltage；Further, being provided with passive PFC module to lift power supply
Efficiency；Further, whether the work of DC-DC conversion modules realizes control by control module, and the control module has several
According to the signal of those function ports, the function port being connected with external module, controls whether DC-DC conversion modules export, and
When response circuit in multiple abnormal conditions, protect subsequent conditioning circuit safety, be not in because of subsequent conditioning circuit excessively stream, short circuit, overvoltage
Situation about directly burning Deng exception；Further, be provided with filtration module and sampling module in outlet side, make output voltage electricity
Stream held stationary.
All such as above-mentioned advantages, the present invention possess brilliance no matter from technical, practicality or economy

Description of the drawings
Fig. 1 is the theory diagram of high frequency switching rectifier module of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing, application scheme is further described：
A kind of high frequency switching rectifier module, with input and outfan, which includes being sequentially connected to the input and defeated
EMI lightning-protection modules 1, full-bridge rectification module 2, passive PFC module 3, DC-DC conversion modules 4 and the filtration module 5 gone out between end,
The DC-DC conversion modules 4 are controlled by a control module 6, and the control module 6 is connected to filtration module 5 by a sampling module 7
Outfan, the control module 6 are provided with the function port that several are connected with external module.
The function port of the control module 6 includes flowing signal input port 61, excess temperature signal input port 62, and mistake
Pressure Guo Liu short-circuit signals input port 63, the excess temperature letter signal input port 62 are used for the signal for obtaining temperature abnormality, and
When control power supply power output or stop output；Equally, over-pressed excessively stream short-circuit signal input port 63 be used for obtain overvoltage,
The circuit abnormality signal of excessively stream and note, and when control power supply power output or stop output, protect subsequent conditioning circuit peace
Entirely, be not in because subsequent conditioning circuit excessively stream, short circuit, overvoltage etc. are abnormal and situation about directly burning.
The control module 6 is provided with the FPDP 64 to external module or equipment feedback data, can be anti-to external monitor
Feedback data, as watch-dog to the control of integrated circuit according to one of..
Above-mentioned preferred implementation should be regarded as the illustration of application scheme embodiment, all and application scheme thunder
Technology deduction that is same, making approximately or based on this, replacement, improvement etc., are regarded as the protection domain of this patent.
