[Objective] To explore the construction of the “Power Electronics Technology” course simulation test platform under the background of agricultural electrification, and to improve the problems in the teaching process, such as the insufficient combination of students’ theory and practice, and the lack of obvious improvement of experiment in promoting teaching effect.[Method] Based on the MATLAB/GUI platform, the basic platform for simulation experiment of four types of converter circuits was designed and implemented. Using the simulation experiment platform, students can modify key parameters, observe the waveform curves of key points, realize the analysis and research of simulation results, and deeply understand the significance of the experiment to improve the application level of combining theory with practice. [Result] The virtual simulation experiment system replaces the traditional instrument and equipment experiment, avoids the uncontrollable factors such as equipment failure and component aging, especially is not limited by time and place, and lays a solid foundation for students to apply innovative power electronics technology in the field of agricultural electrification. [Conclusion] Combined with the traditional teaching method and the reasonable use of computer simulation technology, the simulation experiment teaching can not only solve the differences in students’ learning habits and methods, but also improve the efficiency of teaching and learning, improve students’ learning interest and cultivate students’ self-management ability, which can lay the foundation for improving teaching quality and creating first-class courses.
