摘　　要：为了提高HL-2A装置的物理实验参数,二级加热功率将达到10MW,需要开发新的高压大功率电源来满足不同的加热系统的要求。采用国际上近些年发展起来的PSM技术和快速开关元件,研制基于高功率固态技术的高压电源并进行了PSM单元制作,其输出参数最高达15kV/100A。对此电源使用的PSM控制原理,开关电源模块的研制以及28个开关电源模块串联调节等情况作了描述。测试结果表明,该电源输出电压、电流、输出直流侧有效高频和关断快速性等参数达到了设计要求。In order to improve the experimental parameters of the HL-2A device, the capability of the auxiliary heating system should reach 10 MW. Some new high voltage and large power systems should be required to meet different systems. High voltage power supply based on PSM technique and fast switch elements（IGBT）developed in these years has many features. We developed one PSM unit of which the output could be up to 15 kV/104 A. Moreover, we analyzed the PSM control principle, tested the switch power supply module,and discribed the modulation of 28 SPS modules connected in series. The results show that the parameters about the output voltage and current, the high frequency, the fast switching can meet the design requirements.
