Bu proje Teknofest Efficiency Challange kapsamında düzenlenen Hidromobil kategorisinde ben ve arkadaşım Murat ile birlikte tasarlamış olduğumuz EYS(Enerji Yönetim Sistemi)'dir.
EYS1.0 sistemimiz Hidrojen yakıtından gelen 48V ve bataryadan gelen 72V gerilimlerin akımları ayaranabilir olacak şekilde bir 72V çıkış gerilimi vermektedir. Bu sistemimizde 3 tane buck converter ve 1 tande de boost converter kullanılmıştır.
- Buck Converter'lar:
- 72V/24V@6A
- 72V/12V@3A
- 24V/5V@3A
- Boost Converter:
- 48V/72V@7A
Bu sistemimizi gerçeğe dönüştürmüş olsak da yaptığımız bir çok hata dolayısıyla çalışmamıştır. Bunun için bir sistem daha hazırladık. Bu da EYS2.0 sistemimizdir.
Bu sistemimizde ise öncekinden farklı olarak sadece 2 tane boost converter kullanılmıştır. Çünkü akım yükü iki converter'a dağıtılarak sistemin verimi arttırılmaya çalışılmıştır. Burada iki converter'ımız da hidrojen yakıtından gelen 48V gerilimi 72V gerilime çevirmiştir. Akım kontrolü hala vardır.
Boost converter: 2x 48V/72@15A
Bu sistemimiz ise PCB tasarımında çıkan hatalardan dolayı üretilememiştir.

Questions
How big is the EYS PCB?
It measures 159.8 × 159 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EYS use?
123 parts, built around the LM2576HVS-5, PMEG100V100ELPDZ, CSD19534Q5A and MBR340. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the EYS KiCad files?
From the YatagacLapotk/EYS-EMS repository on GitHub, at the commit this page was made from: the board is EYS1.0/EYS.kicad_pcb and its schematic EYS1.0/EYS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EYS design in my own project?
Its repository states no licence, so its author keeps all rights: ask YatagacLapotk before reusing the design.
