Course description and aims

This is a laboratory course covering the following topics: high-voltage equipment, plasma, surge propagation, AC motors and generators, power electronics, electric power system analysis, and magnetically suspended motors, which are based on the electromagnetic theory and electrical circuit theories.
Through experiments and simulations, students deepen their comprehension of subjects and develop the abilities required of electrical engineers. Additionally, through this experiential learning, students will develop practical skills that are essential to become successful engineers and researchers. These include teamwork, leadership, and communication skills; safety training and experience with electrical devices and machines; methods to obtain and process data; and the ability to draw conclusions from findings and write technical reports.

Student learning outcomes

By the end of this course, students will be able to do the following.
1. Understand the basic principles of pulsed or AC high-voltage generation and develop practical skills in the operation, measurement, data acquisition, and analysis of high-voltage equipment using a circuit simulator.
2. Explain the characteristics of thermal and non-thermal plasmas, and their applications. Measure plasma using electrical or optical methods.
3. Understand the basic properties of electric surge propagation in electric power system and explain the differences between distributed and lumped parameter circuits.
4. Understand the mechanisms of a DC circuit breaker that uses power semiconductor devices, and analyze the fault voltage and current values in an electric power system.
5. Understand six- and twelve- pulse rectifier systems and explain the roles of the inductor and capacitor used in a semiconductor power converter.
6. Understand the working principles of an induction motor based on measurements of the slip frequency and secondary current. Explain the basic characteristics of synchronous generators based on the results of a no-load test and short-circuit test.
7. Understand the principles of magnetic levitation and magnetic bearings using iron- ball-levitation equipment.

Class flow

Students work in teams throughout this course and conduct experiments with seven themes twice weekly in a two-period session. Each class is spent preparing and carrying out experiments, analyzing data, or writing reports. Each report must be submitted by a specified date. Students must read the experiment manual before the start of each experiment to ensure safety and smooth operation.
