Pspice software has powerful function schematic drawing, circuit simulation, functional, graphic post-processing functions and components production function symbols to graphically input, the circuit automatically checks, generate charts, simulation and calculation circuit. Its use is very extensive, not only can be used for circuit analysis and optimization of design, can also be used in electronic circuits, circuits and signals and systems courses in computer aided instruction. And PCB design software with the use of electronic design automation can be achieved. Be recognized as general-purpose circuit simulation program of the best software, have broad application prospects. This thesis through Pspice powerful simulation capability to realize the three-phase fully-controlled bridge circuit,using the software to set up a real-time simulation model, then transient analysis . According to the simulation results of the characteristics of their circuit analysis, comparison, better control of three-phase full bridge rectifier circuit theory and circuit characteristics of understanding.
