摘要
提出一种基于80C552微控制器的高频电刀功率控制系统,对输出功率采用两级控制的方法,分别控制调节功放电路的工作电压和控制功放电路的驱动脉冲信号,其中前级电压控制包含对电网电压波动的补偿。实验结果表明,此功率控制系统具有很好的性能。
A power control system of the solve the problem of output power fluctuation. electrosurgical generator based on 80C552 micro-controller is introduced to Two levels control is adopted, separately controlling the work voltage of adjusting power amplifier circuit and driving pulse signals of commanding power amplifier circuit, of which the first one contains compensation to AC voltage fluctuation. The experiment result shows that the power control system performs better.
