基于有限状态机的电力电子电路仿真方法的研究

Study on Modeling Method of Power Electronic Circuits Based on FSM

仿真是研究电力电子电路的一个重要工具,以往对电力电子电路控制回路仿真多采用试凑法,既费时.又容易出错。针对这种情况,该文根据有限状态机理论提出了一种建立电力电子电路控制回路仿真模型的方法。这种方法简单、方便、准确,几乎适用于所有的电力电子电路控制回路的仿真,是一种系统的方法。文章通过具体电路利用Matlab提供的S imPower-System s和Stateflow进行了仿真,从而说明了这种方法的建模过程,并证明了其正确性和有效性。

Simulation is an important tool for the study of power electronic circuits. For carrying out the simulation, the model of its control circuits is built by trial method usually. This method is not only time comsuming, but also goes wrong easily. This paper presents a simulation method based on the theory of FSM, which is a systematic method, and has the merits such as simple, convenient, accurate and suitable for the simulation of almost all kinds of control circuits of power electronic circuits. An example has been demonstrated to illuminate the process of building the model by SimPowerSystems and Stateflow provided by Matlab.
