Power Supply Systems
FEKT-CNEZAcad. year: 2019/2020
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.
Learning outcomes of the course unit
The graduate is able to
o describe parasitic properties of real electronic components and evaluate their impact on power supply properties
o compare properties (qualities) of different electronic components and choose appropriate on for target application
o explain functionality of both linear and switched mode power supplies
o choose suitable power supply topology (both linear and switched) according to the design needs
o calculate values of and requirements on basic components of power a supply
o use basic CAD tools for power supply design
o design a protection and cooling for a power supply
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.

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 all the laboratory and computer practices, he must elaborate and deliver all protocols and individual project, all in satisfactory quality. Students can gain up to 20 points during laboratory exercises (protocols are evaluated), up to 10 point for active work on PC exercises, up to 20 points for elaboration of individual design project and up to 50 points at final exam.
