摘要
空间电推进电源处理单元是组成电推进系统的关键设备之一,它是多电源组合、输出功率大、电压高及时序控制的复杂电源变换产品。以离子电推进系统配置的电源处理单元为例,叙述了输出功率为1 kW,屏栅电源输出电压达到1 000 V的各功能电源的电路设计,并给出了实验电路的测试结果。
The power supply unit is a one of the important equipment of space electric propulsion system.It is complicated power supply that composed many power supplies;provide high output power,high output voltage,and time sequence control.This paper is take ion electric propulsion power supply unit as an example,describing electric circuit design that provide 1 kW,the screen power supply output voltage arrive at 1000V,and gave the experiment the test of the electric circuit result.
