Courses

Introduction to Circuit Theory and Laboratory provides electric circuit analysis theories and the related experiments. The electric circuit theory is the most important and fundamental theory in electric and electronic engineering. In this course, electric circuits are analyzed, which composed of resistors, inductors, capacitors and Op Amp in linear operational region. The circuits are analyzed using Kirchhoff's current law or Kirchhoff's voltage law. The equivalent circuit and maximum power transfer are introduced using Thevenin and Norton theorems. Transient response and energy storage and discharging are described in analysis of RL, RC and RLC circuits. In experiments, electric and electronic measurement equipments are introduced, and their working principles and manipulations are demonstrated and practiced. The voltages and currents of the circuit elements are measured by standard measurement methods. Each chapter topic related circuits are designed and measured, then the two results are discussed. Also, in projects, application oriented circuits are designed and fabricated in order to enhance the design ability and engineering intuition. 

The purpose of this lecture is to introduce fundamentals of electric energy systems. WIthin this lecture, fundamental subjects of power and energy systems will be addressed including three-phase systems, power transmission and distribution, generators and transformers, renewable energy and energy storage systems, and emerging DC transmission and distribution technologies.

To fully exploit the potential of power electronics towards a sustainable society, not only engineers working in the development of improved and new devices but also application engineers in the field of power electronics need to understand the basic principles of power semiconductor devices. Furthermore, since a semiconductor device can only fulfill its function in a suitable environment, interconnection and packaging technologies with the related material properties have to be considered as well as the problem of cooling. This lecture introduces structures, principles, and characteristics of modern power semiconductor devices and addresses application-oriented issues related to, e.g., reliability, packaging, gate drive units, and failure mechanisms.
