摘要
基于MiddleBrooksExtraElementTheorem,分析了输入滤波器与DC/DC变换器之间的相互作用。给出输入滤波器的设计准则:既能限制谐振峰值和保证稳态滤波效果,同时不影响变换器稳定性和抗扰能力,并给出单级式输入滤波器和多级式输入滤波器的具体设计方法。仿真和实验表明,按该方法设计的输入滤波器,具有体积小、重量轻、损耗低、谐振峰值低及衰减速率快等优点,在开关变换器场合具有重要应用价值。
Based on the MiddleBrook抯 Extra Element Theorem, it analyzes the interaction between input filter and DC/DC converter. Design principles of input filter is proposed, which can limit the filter resonant peaking and have good steady filtering effect, and won抰 degrade the stability and the performance against disturbance of DC/DC converter. Detailed design methods for single-section input filter and multiple-section input filter are also presented. Simulation and experiment show that the input filter designed according to the given methods has the merits such as small volume, light weight, low loss, low resonant peaking and high attenuation speed, and has important application value on switching conversions.
