电力电子变换器主电路拓扑辨识型

针对电力电子主电路拓扑辨识这一目标，提出了两种辨识方法。首先，利用开关支路电流变量为零或非零的信息可确定开关通断状态这一基本原理，通过检测一组拓扑线性无关的开关支路电流变量，可以实现电力电子电路的拓扑辨识。另一方面，基于电路的拓扑向量在不同电路拓扑中变化规律各不相同的基本事实，通过对最简拓扑向量的选取、验算及监测，可依据较少的检测量而实现电力电子电路的拓扑辨识。这两种方×法分别适用于复杂或简单的电力电子电路。

Topology Identification for Power Electronic Circuits

This paper proposed two identification methods of circuit topology for power electronic circuits. First, Based on the fundamental element that the state of a switch can be estimated by itself current, an identification approach can be realized by measuring a set of topology linearity irrelevant circuit state variables. With the fact that there are some topology vectors that vary with different formula in each circuit topology, another identification way can be carried out by selecting and measuring the best topology vectors. The two identification methods are applied to complicated or simple power electronic circuits, respectively.
