Three-phase full-bridge control rectifier circuit plays animportant role in the modern power electronic technology. The simulation model of three-phase bridge controlled rectifier circuit is established with the visualization simulation tool Simulink of Matlab and by full-bridge control rectifier circuit theory. The dynamic simulation and analysis ofoutput voltage, controlling angle, fault phenomenon and load characteristics were performed. The results show that the simulating model is correct, andhas a series of merits such as high speed, agility, convenience, intuition and so on. Therefore, an efficient auxiliary implement is offered for the design of power electronic circuit.
