Regulovatelný laboratorní zdroj pro napájení automobilových elektronických systémů

Abstract

This bachelor's thesis is focused on the design and realisation of laboratory resources that will be used to power automotive systems. In agreement with the supervisor, the source will have one stabilized 5 V output with a maximum current of 2 A, one stabilized 12 V output with a maximum current of 4 A and a regulated output of 0 to 30 V with a regulated current limit of 0 to 3 A. Due to the requirement of minimum ripple I chose linear supply for all outputs. This results in a simpler connection and design than the switched-mode power supply, but also in poorer efficiency and the resulting greater heat loss. The work is divided into several parts. In the first part the issue of linear sources and their main parts will be theoretically described. In the next part, the simulation of all circuits is made to verify the functionality. In the last part the circuits are made and the control measurement is performed.
