Research on Modeling and Simulation of Power Electronic Circuits Based on MATLAB

Abstract

the example of three-phase bridge controlled rectifying circuit discussed the method of the utilization of MATLAB SIMULINK on the modeling and simulation of power electronic circuits, and gave the simulation result waveform, verifying the convenience, intuition, high-efficiency, high speed, genuineness and accuracy of this method. This method can also make modeling and simulation on quite complex circuits, power electronic conversion system, and electric drive automatic control system. The systematic modeling is very similar to the design process of the actual system. Users can get the simulation results of the system quickly without programming and the deduction of mathematical models of circuits and systems. The analysis on the simulation results can transform the system structure or modify relevant parameters in order to make the system get the required results and performance, which can greatly accelerate the analysis or design process of the system.
