开关函数平均法——开关变换器分析方法的改进

Switching Function Average Approach-An Improved Method to Modeling Switching Converters

本文提出了一种新的建立开关变换器分析模型的方法，命名为开关函数平均法。与已有的分析方法相比，该方法推导简单，精度高，可适合于各种不同的开关变换器，并可方便地建立小信号和大信号拢动的统一模型。

The paper develops a new approach to modeling switching converters, named switching function average approach. Compared to existing ones, the approach has a simple deduction, a high precision, a strong adaptability to various switching converters, and a unified analysis of small-signal and large-signal perturbance.
