Abstract

This paper takes 2450MHz/1KW solid-state source as the control object, and designs a control system with STM32F103 as the control core. On the basis of analyzing the system requirements and main functions, the design of the hardware circuit and software flow is explained, and the test and result analysis are carried out. The system uses ADC to sample the analog signal and cooperates with DMA to detect the power and temperature of the solid-state source, which realizes the function of real-time monitoring. Use the buzzer and quick switch to realize the protection function of the system when the power and temperature are too high. Using the single-chip microcomputer to control the operating frequency of the fast switch, two working modes of steady state and pulse are realized. Use the voltage-power fitting function and the PID control algorithm to realize the control function of the power output. Experiments show that this design meets the requirements of a 2450MHz/1KW solid-state source control system, with high control accuracy and practical value.
