| Abstract: | A new design about the microwave physiotherapeutic device based on PIC16F877 MCU control. This paper analyzes the working principle of the system, then puts forward the scheme of power adjusting based on a closed loop control system. At the same time the design of hardware circuit is accounted for in detail, which includes data collecting, D/A converting and power adjusting. Moreover, the characteristics of soft design are also presented clearly. This device can provide power from 30W to 150W, and has digital display and alarming functions. |
