Application of Multisim Simulation Software in Power supply Design

The article analyzes the problems in the current electronic technology course teaching and experimental training. On this basis, it explores the application of Multisim circuit simulation teaching in the power design course. The simulation technology can make the analysis of electronic circuit accurately and quickly completed on the computer and overcome the limitations of the components and instruments of the laboratory, it also breaks through the limitation of time and space. This paper focuses on the innovative application and skill of Multisim simulation software in power supply design, which has great help to the design of power supply. At present, the traditional classroom teaching in vocational colleges is a common phenomenon. Teachers impart some abstract and theoretical knowledge to the students. The complicated theoretical knowledge and traditional teaching methods make the students be afraid of the electronic technology, so that have no willing to learn it actively in class. Although we have mastered a little circuit principle in class, we do not have a deep understanding of the electronic circuit knowledge, which leads to a weariness of learning and a loss of interest in the course of Electronic Technology.The virtual simulation experiment system based on Multisim is helpful to promote teachers to improve teaching methods, stimulate students' interest in learning, improve teaching effect, and improve students' ability to analyze and solve problems. On the basis of students' own ability, they can effectively develop their subjective initiative and develop their creative potential, which is conducive to the matching of practical training equipment and actual production equipment in higher vocational colleges and universities, so as to achieve the purpose of cultivating and training students with advanced , sophisticated and high-tech practical techniques. Simulation Teaching Practice of Multisim Power Supply Circuit In order to verify the role of Multisim simulation in teaching practice, the comparative teaching was carried out in the course of Electronic Technology. Multimedia Multisim simulation teaching was used in the experimental class, added with the experimental training of physical equipment and the simulation practice in the computer room. While the ordinary class carries out regular theory teaching and the experimental training of the physical equipment.In the learning process of the experimental class, first of all, from studying the use and characteristic analysis of each component to the circuit analysis and function research of the course, the Multisim software is used as far as possible to guide the explanation. Then the students are trained to use Multisim software to design simulation, to discuss a little more in-depth problem for theoretical consolidation, and finally to use physical experimental equipment for skills training.For example, when teaching the design of alarm circuit for traffic lights, we first use computer to simulate the real laboratory workbench, let students observe the experimental results, for example, stimulate students be interested in classroom teaching through demonstration. After a semester of comparative teaching, the general class and the experimental class that implemented the Multisim circuit simulation teaching received the practical training examination and the final examination with the same test paper.Through the questionnaire investigation, the examination of the experiment training and the analysis of the final examination results, the implementation of Multisim circuit simulation in the teaching of Electronic Technology 8th International Conference on Education, Management, Information and Management Society (EMIM 2018) Copyright © 2018, the Authors.
