Power supply design capability measurement method based on exploratory factor analysis

Abstract

The invention discloses a power supply design capability measurement method based on exploratory factor analysis, and the method comprises the steps that a student designs a power supply according to a power supply design requirement, carries out a steady-state simulation experiment and a thermal simulation experiment, and collects experiment result data; missing value processing is carried out on the collected data; factor extraction and factor rotation are carried out, factors are reasonably explained, and potential design sub-capability of a power supply is obtained; a factor score is estimated, a threshold value of the factor score is determined based on the power supply design requirement, and the achievement condition of design sub-capability of the power supply is judged. According to the invention, the sub-capability of the switching power supply design is mined from the performance index data of the power supply design result of the student, the mastery degree of the student on the sub-capability of the power supply design is measured and diagnosed, the student can further improve the weak link, the power supply design can be further optimized, and the solution design and development capability of the student can also be improved. Graduation requirements are met, and students become qualified engineers with rich theoretical knowledge and practical experience.

Description

technical field [0001] The invention relates to a method for measuring power supply design capability based on exploratory factor analysis. Background technique [0002] The output-oriented engineering education concept helps students improve their weak points in learning, promotes students to achieve graduation requirements, and meets the actual talent needs of social enterprises. The "Washington Agreement" puts forward 12 graduation requirements, which have become the standard for various schools to cultivate applied engineering talents. Among them, design and development of solutions is one of the 12 graduation requirements, which is an important ability for engineering students. Students are required to be able to design solutions to complex engineering problems in electrical engineering and related fields, design systems, functional modules or technological processes that meet specific needs, strengthen practical ability, and be able to reflect innovation awareness in t...

Problems solved by technology

However, in traditional power electronics experiments, where students typically conduct verification experiments, design capabilities are taught in a discrete and incoherent manner, with limited exposure to students, resulting in a passive learning environment

Secondly, the experimental evaluation mainly relies on the weekly experimental report, which is highly subjective, and the evaluation result is a single score. Students with the same score cannot diagnose the differences in their knowledge structure and ability, and cannot conduct individualized evaluation. Inability to indicate what competencies or competencies the student should acquire and whether they are achieved
