Dette studentprojekt dækker efterårs- og forårssemestret 2013–2014 (9. og 10. semester) og fokuserer på at designe en tovejs flyback-omformer til en DEAP-generator (dielektrisk elektroaktiv polymer). Arbejdet giver først en introduktion til de energihøstningscyklusser, der er relevante for DEAP-systemer. Derefter gennemgås omformeren teoretisk. For at forbedre effektiviteten seriekobles to siliciumcarbid (SiC) MOSFET'er. Metoder til seriekobling omtales kort, og en gate-balanceringsteknik anvendes for at sikre jævn spændingsfordeling under omskiftning. En prototype af omformeren blev bygget i AAU's laboratorium og afprøvet ved forskellige spændingsniveauer.

This student project spans the fall and spring of 2013–2014 (the 9th and 10th semesters) and focuses on designing a bidirectional flyback converter for a Dielectric Electro Active Polymer (DEAP) generator. The work first introduces the energy harvesting cycles relevant to DEAP systems, followed by a theoretical discussion of the converter. To improve efficiency, two silicon carbide (SiC) MOSFETs are connected in series. Techniques for series connection are briefly reviewed, and a gate-balancing approach is used to maintain even voltage distribution during switching. A prototype of the converter was built in the AAU laboratory and tested at different voltage levels.
