Description
Technical field
The utility model relates to a kind of high-voltage generator, particularly a kind of novel high-pressure generating means that is used for medical diagnostic equipment.
Background technology
At present, the high pressure generator device (like Fig. 1) in the state-of-the-art medical diagnostic equipment (CT, X-ray machine), it is output as the little electric current of high-frequency and high-voltage, and its frequency is 60KHz～250KHz, and voltage is 15KV; (so-called big electric current is also just at moment (20～40ms) output 150mA) for the about 20mA of electric current.
Yet present high-voltage generator still exists: driving power is done not quite, volume is big, high-voltage stability output is not a problem such as very high, and these problems will directly have influence on the definition of imaging.
The utility model content
To the above technical problem of mentioning; The utility model proposes a kind of brand-new high-voltage generator; Make efficient raising, volume-diminished, the high-voltage stability of the type high-voltage generator high, and the adjusting of high pressure is more convenient, to solve the defective of above-mentioned prior art.
The utility model solves the technical scheme that its technical problem adopted: a kind of novel high-pressure generating means, it is characterized in that, and form by power driving circuit, high-voltage converter and X bulb tube three parts;
Said power driving circuit adopts the decentralized power-supply mode, is about to an original high-power drive circuit and splits into N piece low-power drive circuit, respectively driving N piece high-voltage converter;
Said high-voltage converter adopts modularization management, and each high-voltage converter module can both be exported the big current signal of certain low-voltage separately; The output of N piece high-voltage converter; Then couple together with series system, unified being placed in the oil tank is used to drive said X bulb tube; And the designer can be required according to the X bulb tube voltage, calculate the quantity N select the high-voltage converter module for use.
The beneficial effect of the utility model is:
(1) because the utility model has adopted the decentralized power-supply mode; Can make power driving circuit in the high-voltage generator be designed to operating frequency higher (250KHz-1MHz), power output is corresponding also can reduce, this makes the power driving circuit volume in the high-voltage generator reduce greatly.
(2) compare with existing high-voltage generator, form, thereby the stability height of output voltage because the high voltage of this device output is low-voltage overlapped in series by some groups of outputs, and the volume of HVTank also can design littler.
(3) the utility model adopts modularization management, and the designer can calculate the quantity of selected module easily according to X bulb tube required voltage, makes whole system more possess hommization with personalized, and is more suitable for being applied in the mobile X-ray machine.
Description of drawings
Fig. 1 is existing high pressure generator system configuration sketch map.
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 2: a kind of novel high-pressure generating means, it is characterized in that, form by power driving circuit, high-voltage converter and X bulb tube three parts;
Said power driving circuit adopts the decentralized power-supply mode, is about to an original high-power drive circuit and splits into N piece low-power drive circuit, respectively driving N piece high-voltage converter;
Said high-voltage converter adopts modularization management, and each high-voltage converter module can both be exported the big current signal of certain low-voltage separately; The output of N piece high-voltage converter; Then couple together with series system, unified being placed in the oil tank is used to drive said X bulb tube; And the designer can be required according to the X bulb tube voltage, calculate the quantity N select the high-voltage converter module for use.
In the application of medical diagnosis large-scale X machine commonly used at present, the required voltage of X bulb tube is 15KV, if individual module is output as 3KV, so can know that through calculating the module number that needs to adopt is: N=5.
