Electronic Circuits (17KBBEO)

Lecturer:

Tutor:

Supervisor:

Department of Biomedical Technology

Synopsis:

Basic power electronics, power supplies units including electrochemical supplies, rectifiers, stabilizers, common types of motors, basic distributions of electricity, types of electric systems and connecting of electric appliances with sight on medical purposes. The knowledge will be checked in the laboratory by mean of practical examples during the work in the laboratory.

Study Objective:

The aim of the education of subject power engineering on FBMI is to have knowledge from basics of power electronics and connecting of electric appliances with sight on medical purposes. The aim is not to gain detail knowledge with subject extension, but to introduce the students with the basics of power engineering. It is important to understand the physical basis of the problem.
