Abstract
In this thesis an inverter prototype which enables bidirectional grid connection with a single stage, proposed by Eckart Hoene in context of the EnerConnect project by Fraunhofer \ac{IZM} is designed, assembled and commissioned. The theoretical foundation of \ac{GaN} switches, the flying capacitor principle and the fundamental function of the novel topology are investigated and documented. Instead of the proposed topology, a simplified version with bidirectional devices substituted by two conventional anti-serial \ac{GaN} switches, no flying capacitor and only \ac{GaN} \ac{HEMT} devices instead of additional \ac{MOSFET}s is designed and assembled. The static control principle and the function of the simplified proposed topology is then verified in \ac{DC}-\ac{DC} laboratory experiments.
