For the shortage of teaching resources on average in power electronic technology practice teaching, in order to improve teaching quality and meet the needs of various teaching means, 〖JP〗Visual C++ and Matlab is used to develop simulation experimental platform for power electronics. Simulation experiment platform can be used without other player software installation. Through repeatedly debugging parameters of the circuit and observing the effects of parameter changes on the circuit simulation results, students′ ability to use knowledge and to innovate is improved. 
