Abstract Details

2023, Doctor of Philosophy (Ph.D.), University of Dayton, Electrical Engineering.
Power electronics devices usage is increasing with the fast development of semiconductor technology. From renewable energy areas to transportation applications, power converters are widely used to achieve power conversion. Thus, the power converter efficiency is important since the large amount of power usage in these applications. Besides, the power density is another key parameter for the power converters due to the concern of the converter size. In this work, the improvement of converter efficiency and density are achieved by adopting new converter topology and using the wide band gap semiconductor devices such as GaN and SiC. Also, the resonant converter performance evaluation method is proposed. Firstly, a new switched-tank modular (STM) topology with zero voltage switching (ZVS) capability is developed. Secondly, a new method helps compare and analysis different topologies is proposed. Finally, a converter for power process in fuel cell based electric drone is designed using the GaN device.
