Problems solved by technology

[0003] In the prior art, the electron gun titanium pump on the accelerator system requires a power supply with small size and light weight, and a working voltage of 4000V, which can cope with unexpected situations such as heavy load or sparking, and cannot work in the flyback converter mode, corresponding to the existing high-voltage Power supply, in the prior art, has a complex structure, large volume, high power consumption, and poor output voltage stability. Therefore, we propose a small DC high-voltage power supply for lightweight accelerators to solve the above problems

Abstract

The invention discloses a small direct-current high-voltage power supply for a lightweight accelerator, and the power supply comprises an input rectifying and filtering circuit, and is characterized in that the input rectifying and filtering circuit is connected with a flyback high-voltage high-frequency transformer, a three-terminal off-line PWM switch and an isolation AC / DC power supply module, and the flyback high-voltage high-frequency transformer is connected with a rectifying diode; the isolation AC / DC power supply module is connected with the isolation sampling feedback circuit and the isolation DC / DC power supply module, the rectifier diode is connected with the output capacitor and the precision high-voltage resistor, and the isolation sampling feedback circuit and the isolation DC / DC power supply module are both connected with the external transmission signal acquisition circuit, so that the power supply is smaller in size while ensuring that the output voltage meets the use requirement of the titanium pump; the installation is convenient, efficiency is high, reliability is high, output direct current is more stable, and ripple waves are small.

Description

technical field [0001] The invention relates to the technical field of lightweight accelerator equipment, in particular to a small DC high-voltage power supply for lightweight accelerators. Background technique [0002] The X-band lightweight electron linear accelerator for industrial non-destructive testing is a high-energy ray detection device. Compared with the traditional S-band industrial electron linear accelerator, the X-band accelerator has the characteristics of small size and light weight, and can be applied to complex working conditions, especially In an environment where the detection environment is complex, the working space is limited, the deployment is difficult, and the mechanical assistance equipment cannot be deployed, the lightweight accelerator can be deployed only by manpower. Component protection, lightweight accelerators are mainly suitable for online in-service testing of large petrochemical installations, on-site testing of nuclear power containment ...
