To improve the stability of Arcjet discharge plasma in low current and high voltage mode, research on the demand of output characteristics of Arcjet Power Conditioning Unit was conducted. In this paper, based on PWM invertors and current mode control, using MOSFET as the main power device, an Arcjet Power Conditioning Unit was developed. Through adding a closed loop feedback circuit of output voltage, it can make the output characteristics of PCU be positive resistance to ensure the stability of Arcjet discharge plasma. The experiment indicates that this PCU can make Arcjet engine work at high voltage mode (100 V, 10 A) and ensure the stability of arcjet discharge plasma. Finally, it provides the experimental data of Arcjet when working.

为了解决小电流、高电压下电弧火箭等离子体的稳定性问题，研究了电弧火箭发动机对电源调理单元的输出特性要求，基于逆变电源脉宽调制技术与峰值电流型控制原理，以MOSFET为主功率器件，研制了一台电弧火箭电源调理单元，给出了Arcjet工作时的实验数据，通过增加PCU输出电压的闭环反馈电路，可以使PCU的输出外特性呈现正阻性，保证电弧的稳定燃烧，实验结果表明，该电源调理单元能使电弧火箭发动机达到高电压工作模式(100V， 10A)，保持电弧工作的稳定性。
