TESLA TRANSFORMER 300 KV 200 kHz BY MICROCONTROLLER CONTROL

Abstract

In this research, the researchers studied the development, design and construction of a tesla transformer 300 kV 200 kHz by microcontroller control set and developed learning activities by using experimental exercises. The purposes of the research were to study the suitability and the experimental application of the learning activities in the electromagnetic field teaching materials as well as to develop a learning management plan and apply the experiment of learning activities in the Electromagnetic Field course. The findings could be used for educational purposes and as an experimental device in high voltage laboratories for teaching and learning. The results of the research were as follows: 1) The learning activities according to the practice model and an application in the teaching materials for the electromagnetic field course comprised 5 steps: educational process and data collection, design process and creation of a high voltage rectifier circuit and a showdown, procedures for studying and experimenting with the implementation of principles and worksheets, experimental and standard reference procedures and analysis of steps and summarization of the results which made the students understand the lesson more; 2) The overall level of appropriateness of the activities assessed by experts was at a high level (= 4.40, S.D. = 0.48); and 3) For teaching and learning, the learning achievement after the lessons received the average score of 59.76 out of 70 points (85.37 %). The application in the teaching materials for the Electromagnetic Field course had the efficiency of 84.64 / 85.37, which was higher than the 80/80 criteria.
