Course detail

Power Supply Systems

FEKT-KNEZAcad. year: 2018/2019

The course is strongly oriented on practical knowledge, its aim is to teach students to properly choose type of electronics power supply and design it. Students get familiar with basic electronics components used in modern power supplies (both active and passive) including their parasitic properties. Different topologies of linear and switched mode power supplies are discussed. Isolated, non-isolated and autonomous power supplies are covered. Students perform simulation of elementary power supply circuitries, design a simple power supply using available CAD tools and design a PCB for it including manufacturing data output.

Prerequisites

Students are expected to have knowledge of basic electronic components (resistor, capacitor, inductor, transformer, diode, bipolar and unipolar transistor, tyristor) and basic knowledge of differentiation and integration.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to prepare a single project during the course.

Assesment methods and criteria linked to learning outcomes

Student must pass the computer practice (10 points for active work) and the laboratory practice and he must elaborate and deliver all protocols in satisfactory quality (up to 10 points). Students can gain up to 30 points by elaboration of individual homework (submitted on tutorials). At final exam students can get up to 50 points.
