Design Of Compact 150kV High Voltage Power Supply With Converter Technique

High voltage power is extensively used in scientific and industrial applications. As one indispensable component, custom designed high voltage power supply can be found in X-ray diffraction, lasers, electrostatic spraying, medical, instruments for spectroscopy, mass spectrometry and many other analytical imaging and process applications. Traditional high-voltage power supply mainly adopts of linear technology, which has low conversion efficiency, large volume, heavy, and inconvenient of operation and maintenance.This paper describes a high voltage design using Switch Mode Power Supply technique. Silicon-Controlled Rectifier (SCR) was employed as a switching unit. The main improvement consists in stable performance and fine applicability. Less weight, easy to produce install and remove, easy to get the productive material, the simplicities of the power converter and the minimum industrial cost are the main features of the Power supply.The introduction part describes the background of the subject and the main research work. The second part introduces the theoretical basis of this power supply system design in detail, and the whole structure diagram of the power is given. The third part mainly introduces the design and operations of the experiment, where analyses of the experimental results are listed. In the conclusion part of this paper, the output capacity, structure and device parameters of the circuit are discussed, which provides a theoretical basis for the future work.
