The necessity and difficulty of real - time simulation of power electronic devices were analyzed, and an uni-versal switching model was deduced. A real - time simulation system of power electronic devices was designed based on this model, and it was achieved through SOPC technology. The simulation test of a MOSFET was done, the result was compared with the experimental result,which proved the correctness of this system. The system takes full advan-tage of parameters and waveform curve provided by the device manufacturers.
