BROŽIČ, ANDRAŽ (author), Žemva, Andrej (mentor)

Glavni namen pričujoče magistrske naloge je razviti krmilno elektroniko večjega baterijskega modula. Skozi nalogo so razložene vse zahteve in funkcionalnosti, ki jih mora tiskano vezje opravljati. Vsak del vezja je posebej predstavljen, izbira komponent pa računsko podprta. V uvodu se dotaknemo samega področja letalstva, omenimo nekaj zgodovinskih prelomnic na tem področju in se posvetimo problematiki v letalstvu, s katero se soočamo v današnjih časih. Predstavljeni so razlogi in morebitne rešitve omenjene problematike. Na kratko opišemo tudi inovativno slovensko podjetje, pionirju na področju aviacije, Pipistrel. V naslednjih poglavjih preidemo na same zahteve in pričakovano funkcionalnost elektronike, ki je tema te zaključne naloge. Predstavljena sta celoten baterijski modul in blokovna shema glavnih predvidenih delov tiskanega vezja. V nadaljnjih poglavjih sledita teoretično ozadje in razlaga komunikacijskih protokolov, uporabljenih v samem projektu, z večjim poudarkom na komunikacijskem protokolu CAN. Dotaknemo se tudi teoretične in računske razlage delovanja napetostnih pretvornikov, s poudarkom na stikalnih napetostnih pretvornikih navzdol. Sledita razlaga in opis posameznih delov načrtovanega tiskanega vezja z vsemi pripadajočimi vezalnimi shemami. Prav tako je prikazana dejanska implementacija tiskanega vezja v celovit sistem. V zadnjem poglavju je predstavljeno še testiranje, ki je bilo izvedeno na tiskanem vezju, in komentar rezultatov.

Abstract

The main goal of this master's thesis is the development of controling electronics for a larger battery module. Through the assignment, all requirements and functionalities that a printed circuit must perform, are presented and explained. Each part of the circuit is presented separately, and the choice of components is computationally supported. In the introduction, we touch on the field of aviation, mention some of the historical turning points in this field and focus on issues of aviation, that we are facing nowadays. The reasons and possible solutions to this problem are presented. We also dedicate a few words to the innovative Slovenian company, a pioneer in the field of aviation, Pipistrel. In the following chapters, we move on to the requirements themselves and the expected functionality of electronics, which is the main topic of this thesis. The entire battery module is presented, as well as the block diagram of the main parts of the printed circuit board. In subsequent chapters, we move on to the theoretical background and explanation of the communication protocols used in the project itself, with greater emphasis on the CAN communication protocol. We also touch on theoretical and computational explanations of the operation of voltage converters with an emphasis on buck switching converters. In the following chapters, an explanation and the description of the individual parts of the planned printed circuit board with all associated wiring diagrams are presented. The actual implementation of the printed circuit board in a complete system is also shown. The last chapter presents the testing performed on the printed circuit board and comments on the results.
