Analysis and Simulation of Output Characteristics of a Rectifier Circuit

The rectifier circuit is an important part of the excitation system in a synchronous generator. It has significant effect on power system. In this paper, on the basis of circuit analysis, the relationships between the output voltage and flow angle and load characteristics in the three- phase bridge fully controlled rectifier circuit were studied using simulation software Simulink based on MATLAB. The results show that voltage waveform of both simulation and circuit analysis is identical. Matlab/Simulink provides an effective and convenient method for simulation and analysis of the complicated circuits. And it can be used to replace circuit experiment and applied in the design and adjustment of circuits.
