高频电刀输出功率的测试与分析

摘要

目的:测试高频电刀标称负载下的输出功率,分析造成输出功率过低的原因.方法:采用峰-峰电压值测量的测试方法,检测并计算功率误差.结果:通过检测发现存在功率输出控制电路的缺陷,致使高频电刀功率低于标准限定值.结论:对于测试功率过低的高频电刀宜进一步改进设计,提高功率准确性.%Objective:To test power of ESU under nominal load consistency, and analyze the possible reason for under power.Methods: Power error of ESU is tested and analyzed based on the way: peak-to-peak voltage test by oscilloscope.Results: Power of the ESU is under the limit of standard.Conclusion: Something should be done to improve the power veracity by modified design.
