| 摘 要： | 本文将电路理论中的对偶变换原理扩展应用于开关变换器电路的对偶分析。文中导出了动态导通比参数、半导体开关管拓扑以及变压器理想模型的对偶形式。应用这些对偶关系，可以较简便地直接将开关变换器及其小信号等效电路模型按照对偶原理分析，求得它们的对偶拓扑。

| Abstract: | In this paper the duality principles of electrical circuits are extended to the switching converter topologies. The duality of transformers (ideal and perfect models) is investigated. In addition, the duality relationships of duty ratio parameters and semiconductor-switch topologies are also given. Applying these relationships, both the switching converter with (or without) isolated transformer and their canonical linearized circuit models can be directly and simply correlated by duality. |
