摘　　要：为全面调试、考核行波管放大器配套的高压电源,需提供20kV高压通断开关来模拟行波管负载行为,因此本文设计了一种基于FPGA的高集成20kV脉冲行波管模拟器用高压电子开关控制器。本文采用FPGA技术设计了PRF脉冲信号,扫频和群脉冲模式,以及人机交互接口。最后,本设计在Actel公司的A3P250芯片上采用VHDL语言实现,并通过示波器进行验证,目前产品已通过了硬件调试验证,运行状态良好。In order to examine the high voltage power supply of Traveling Wave Tube Amplifier （TWTA）, a highly integrated 20KV pulsed TWT electrical controller based on FPGA was introduced. In this paper,ways to generate PRF signals and the met hod of man machine interface implementation were discussed. Besides, ways to implement scan modes and cluster pluses were also presented. Finally, the project was verified on Actel A3P250 FPGA device, and the product of this project has been in use with a good working condition.
