9. Course Prerequisites
10. Course Goals (acquired competencies): Gaining basic knowledge and understanding of the principles of operation, design and applications of basic dc-dc power converter topologies and its parameters, dc-dc power supplies, design requirements and procedures. Acquiring competence and skills to use, analyze, compare, design and test switch-mode power supplies, as well as solving practical application examples.
11. Course Syllabus: Introduction: voltage chopper, control of dc-dc converters with pulse-width modulation (PWM), assumptions used in steady-state analysis. Step-down (buck) converter, genesis, continuous and discontinuous conduction mode, boundary between continuous and discontinuous conduction, output voltage ripple, switching devices voltage and current stresses, effects of parasitic elements on converter efficiency. Analysis of other non-isolated converters: step-up (boost) converter, buck-boost converter, Cuk dc-dc converter, SEPIC and ZETA converters. Bidirectional converters. Full-bridge dc-dc converter: PWM with bipolar and unipolar voltage switching . Non-isolated dc-dc converter comparison. Review of magnetic circuits and transformer models. Dc-dc converters with electrical isolation: flyback, forward, push-pull, half-bridge, full-bridge and current-source dc-dc converter. Control of switch-mode dc power supplies: linearization using state-space averaging, transfer function, stability and compensation of the feedback system, current-mode control, power supply protection.
12. Learning methods: Lectures supported by presentations, examples solving auditory exercises, practical laboratory exercises, preparation and presentation of individual project/seminar assignments, homework.

19. Conditions for acquiring teacher’s signature and for taking final exam Completed practical laboratory exercises and project assignments.
20. Forms of assessment Examination comprises two midterm exams (max 120 min), tests during the classes, and a laboratory exercises test at the end of semester. After successful completion of these tests, an oral examination may be required (max 60 min). The final mark is based on the points collected from all mentioned tests and the class activity. Student project is also required due before the end of the lectures. When mid term exams are not successfully passed, they are replaced by a written exam (max 120 min) during the exam sessions, with other requirements and rules remaining the same. Use of textbooks, any other notes, mobile phones, or other electronic devices, except the calculator, are not allowed.
21. Language Macedonian and English
22. Method of monitoring of teaching quality Internal evaluations and surveys.
