Research on the application of simulation technology in the experimental teaching of high voltage course for electrical majors

For the difficult problems in the experimental teaching of power electronics technology, MATLAB simulation technology is introduced into teaching practice.Take three-phase PWM rectifier circuit as an example, a simulation model is established based on the analysis of the working principle, and parameters of each device of the threephase PWM rectifier circuit are set.And voltage, current and harmonics of three-phase PWM rectifier circuit are compared with diode rectifier circuit.Practical results show that the application of MATLAB in the simulation experiment teaching of power electronics technology courses is beneficial for students to better understand and master basic knowledge, make difficult problems easier to be understand, and actively improve students' innovative spirit and research ability.
