一种空间行波管电源EPC控制器的设计与实现OA

To address the problems of high cost,large volume and insufficient expandability of traditional EPC test equipment for space traveling wave tube power supplies in environmental and life tests,a low-cost,com-pact and highly stable EPC controller based on domestic GD32F103 microcontroller is designed.The device in-tegrates five functions,including bus power control and protection,remote command transmission,telemetry signal acquisition,upper computer communication,and local screen display.By adopting anti-aliasing filtering,oversam-pling technology and digital filtering algorithms,the data acquisition accuracy of it is improved to within 0.06％.A single unit has passed a 30,000-hour continuous ground life test,and works stably throughout the process,which fully meets the engineering application requirements for space EPC ground tests and environmental tests.
