考虑非理想器件模型的电力电子系统状态方程分析法
State Space Method to Analyze the Power Electronics Circuits Considering Devices' Non-Ideal Models
摘要
Abstract
At present, there are some problems in the simulation software of power electronics, such as rough simulation waveforms for device switching transients, non-convergence for stiff systems etc. Hence, our group has proposed an analysis method—discrete state event drive (DSED) based on quantized state system (QSS). In this method, the algorithm based on circuit topology and state is integrated that can identify the switching states of devices and extract state space equations. Thus, a graph-theory-based algorithm that can extract the state and output equations is proposed. It is proved theoretically that the state space equations of power electronic systems are always in norm-form. Furthermore, parameter-structure matrix is proposed. Some discussions are carried out to the problem that every time a switch alters its status, the coefficient matrices of state space equations must be recalculated. Finally, simulation results of classical circuits have verified the proposed method.关键词
