Course detail
Power Supply Systems
FEKT-KNEZAcad. year: 2017/2018
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.
