摘要:

针对椭圆超声功率切削驱动装置的BUCK变换器模型进行优化研究,充分考虑变换器中各元器件的寄生参数对模型的影响,同时对其中LC优化设计进行了较为深入的分析,设计出优化的变换器模型并制作出其对应的验证电路。对该模型中的两个重要传递函数模型的BODE图进行了试验与仿真对比分析,结果证明该模型比较理想地反映了真实电路的动态性能,较好地指导了变换器的设计。

Abstract:

Based on elliptic ultrasonic power cutting driving device of the BUCK converter model optimization research, fully considering the influence of each component parasitic parameters on the model, at the same time the LC optimization design was carried on the thorough analysis, an optimized converter model was designed and the appropriate verification circuit was made. Through analyses of two important BODE diagrams of transfer function model test of the model and simulation analysis, the results prove that the model better reflects the dynamic performance of the real circuit, better guides the design of the converter.

Key words: ultrasonic power cutting drive, elliptical vibration mode, BUCK converter, model
