摘　　要：行波管放大器在卫星通信和国防等领域的应用越来越广泛,行波管电源系统对输出电压稳定性的要求也越来越高,但传统的模拟控制开关电源存在诸多缺点,无法满足需求。为此,设计了一个基于现场可编程逻辑门阵列(field programmable gate array,FPGA)的数字控制开关电源,功率主电路采用Buck型变换器,控制环路采用电压环反馈控制。在MATLAB/Simulink仿真的基础上,结合FPGA对系统整体性能进行测试。结果表明,电源系统在不同工作条件下的输出电压稳定,瞬态响应调节迅速,总体性能满足行波管放大器的设计要求。Travelling wave tube amplifier is more and more widely used in satellite communications,national defense and other fields.The requirements of traveling wave tube power supply system for output voltage stability are higher and higher.However,the traditional analog control switching power supply has many shortcomings and can not meet the needs.To this end,an field programmble gate array(FPGA)-based digital control switching power supply was designed.The main power circuit adopted a Buck converter,and the control loop applied voltage loop feedback control.Based on MATLAB/Simulink simulation,the overall performance of the system was tested with FPGA.The results show that the output voltage of the power supply system is stable under different working conditions,the transient response is adjusted quickly,and the overall performance meets the design requirements of the traveling wave tube amplifier.
