Electronic Equipment Power Supplies

Course Description

The first part of the course will give an overview of energy sources that can practically be used to power electronic devices. For each source selected, an overview of the parameters will be given, which will be compared with the parameters of the other sources. The second part of the course will give an analysis of the regulator parameters with respect to the power requirements of the device. A methodology will be proposed to arrive at concrete solutions as well as an analysis of the good and bad sides of particular types of solutions. The back of the course will provide guidelines for the design of electronic and electromechanical parts of a power source.

Learning Outcomes

  1. Evaluate system power requirements to real electronic circuits and devices.
  2. Evaluate which real electronic circuitry is the optimal solution for powering the system
  3. Assess what real power source should be used to power the system

Forms of Teaching


Lectures are focused on theoretical and practical aspects of key course topics (three hours per week).


Students are obliged to take laboratory exercises (13 hours). During the laboratory exercises, students learn about principles of power supplies.

Grading Method

Continuous Assessment Exam
Type Threshold Percent of Grade Threshold Percent of Grade
Laboratory Exercises 50 % 20 % 50 % 20 %
Mid Term Exam: Written 50 % 40 % 0 %
Final Exam: Written 50 % 40 %
Exam: Written 50 % 40 %
Exam: Oral 40 %

Continuous evaluation encompasses two written exams (midterm and final exam). Students who do not satisfy at continuous evaluation must undertake both the written and oral exam. Students are questioned at the laboratory exercises.
