互联系统中电流模式控制电源模块的大信号建模方法

摘要﹕本文提出一种互联系统中电流模式控制电源模块的大信号建模方法。提出了电流模式控制电路功率级的能量传输模型，并给出了四种基本变换器模型的推导；在仿真方法上，强调必须保留外环的反馈回路，才能保留大信号下系统的瞬态特性。所建模型有望在通过仿真预测、验证互联系统的稳定性方面获得应用。

Abstract: This paper proposes an approach (model) to deal with current-mode-controlled power modules while investigating large-signal interactions among subsystems in a  istributed dc power system. By establishing a family of power stage models that embody nonlinearity to an algebraic operation block and keeping all components along in the external feedback control loops staying in simulation, simulation speed can be dramatically accelerated as well as large-signal dynamic properties can be reflected correctly. Mathematic derivation of the models is presented and simulation tests show the validity of the proposed approach.
