MATLAB-based simulation analysis of the rectifier circuit
Abstract:With the social production and scientific and technological development, the rectifier
circuit in the automatic control system, measurement system and generator excitation system, and
other fields increasingly widespread. Commonly used three-phase bridge rectifier circuit with
full-controlled single-phase bridge rectifier circuit and control circuit. As the rectifier circuit
involves the exchange of signals, DC signals and trigger signals, including thyristors, capacitors,
inductors, resistors and other components, using conventional circuit analysis method appeared to
be quite complicated, high-pressure situations is difficult to experiments carried out smoothly.
Matlab provides a visual simulation tool Simtlink circuit simulation model can be directly set up,
free to change simulation parameters and immediately available to any of the simulation results,
intuitive, eliminating the need for further programming steps. In this paper, Simulink full control
of three-phase bridge rectifier circuit model, for different control angle, the bridge under fault
conditions were simulated analysis. Controlled single-phase bridge rectifier circuit parameters and
the different nature of the work load of the comparative analysis and research, both to further
deepen the three-phase full-controlled bridge rectifier circuit and controlled single-phase bridge
rectifier circuit theory, while for modern power electronics experiment experimental teaching lay
a good foundation.
