To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of high voltage power supply of Symmetrical output, includes input filter circuit, high-pressure modular, for preventing from exporting
The protection circuit that pours in down a chimney, be locally displayed module, this/far control switching circuit, output regulating circuitry and positive output and negative output,
Wherein described protection circuit is separately positioned between the positive output and high-pressure modular and negative output and high-pressure modular.
Further, the high voltage power supply also includes the Remote control interface being arranged on the high-pressure modular, wherein described remote
Control interface controls the high-pressure modular by the computer being communicated with the outside.
Further, the positive output and negative output are to be exported by the way of simulation output individually controls high pressure.
Further, the high-pressure modular is the high-pressure modular structure for being better than 50PPM using ripple 10PPM and stability.
Further, the module that is locally displayed is formed by module one is locally displayed and module two is locally displayed.
Compared with prior art, this programme has advantages below：
1st, to prevent from output end from pouring in down a chimney causing the damage to power supply, it is ensured that the reliability of power supply in the course of the work, this
Conceptual design employs protection circuit；
2nd, using brand-new design theory, to ensure that high stability and low output ripple, this programme preferentially use ripple
10PPM and stability are better than 50PPM high-pressure modular structure；
3rd, to meet the symmetry of positive and negative output high-voltage, power supply is controlled by Remote control interface using computer, computer leads to
Over-fitting formula result of calculation sets High voltage output, ensures the requirement of the high symmetry of positive negative output, has expense low, high symmetrical
Property output the advantages of.
