摘　　要：高频电刀已经广泛取代机械手术刀应用于临床手术中,其电源模块是否能够提供稳定输出电压是确保设备运行稳定、手术安全的关键。开关电源控制技术一直是国内外研究的热点,设计基于DSP的数控开关电源应用于高频电刀在电刀电源设计方面正受着越来越多的关注。本文介绍了基于各种调制芯片、数字信号处理器、单片机控制的开关电源原理和方法,概述了国内外研究现状,并从提高瞬态响应速度、提高稳压精度、简化结构提高集成化程度、提高稳定性并降低成本方面总结了发展方向。High frequency electric knife witch replace mechanical scalpel has been widely used in clinical surgery. Provide a stable output voltage of the power module is the key to ensuring the stable operation of equipment and the safety of clinical surgery. The control methods of switching power supply are an active area of research. Switching power supply based on DSP numerical con- trol is attracting increasing attention with respect to the Electrosurgical. In this paper, we introduced the principles and methods of switching power supply based on Modulation chip, DSP, MCU control. We also summarized the state of the art and the prospect in these respects： increasing the transient response speed, improving the regulation accuracy, simplifying the structure to improve the level of integration, and enhancing stability and reducing costs.
