用于EAST诊断中性束加速极初级电源的设计与仿真

Simulation and Design of Accelerator's Primary Power Supply in DNB for EAST Diagnosis

介绍了用于EAST的诊断中性束(DNB)加速极初级电源的设计方案。该方案所提供的电压在20kV^50kV范围内可调,特别是在35kV^50kV能以大约1kV为单位逐步上调,同时电压纹波系数可控制在5%以内,最后对初级电源进行了仿真。仿真结果表明该方案完全能达到初级电源的设计要求。

Design of accelerator＇s primary power supply in DNB for EAST diagnosis is described in this paper. In the design, the output voltage variation can be controlled between 20 kV～50 kV ,especially stepped between 35 kV～50 kV by 1 kV and meanwhile the ripple voltage coefficient is within 5 %. The simulation of primary power supply verifies that it completely meets the designed specification.
