【Abstract】 In view of the lack of innovative and comprehensive experiments in the existing practical teaching system,an innovative experimental scheme of the current transformer power supply design based on the maximum power tracking is proposed based on the supply of high-voltage transmission cables. The experiment integrates relevant knowledge of circuit theory,high voltage technology,control theory and other disciplines. It consists of five stages: topic selection background,theoretical analysis,algorithm application,hardware design and simulation analysis. Through these,students can understand the theoretical model of current transformer power supply,learn the dual maximum power tracking algorithm based on particle swarm optimization and perturbation observation method to track the maximum power of the secondary side,and master the hardware circuit design method. In addition,students’ software programming thinking is cultivated,so that the optimal results can be obtained intuitively through simulation,and students’ ability to analyze and solve practical problems is improved.更多还原
