As an emerging device used in surgery, Radiofrequency (RF) ablation is widely used in minimally invasive surgeries. In the process of surgery, the system needs to output constant power to ensure the quality of surgery when the tissue location or ambient temperature and humidity change. The hardware of the RF ablation system was designed in this paper, and the power closed-loop control was realized. The system uses a microcontroller STM32F303VCT6 and the dual ADC alternate sampling method to require the RF output signal. The RF output power is obtained by frequency-domain analysis of the sample...
