High-Frequency GaN-Based Inverter Control Design Using PSIM

Gallium nitride (GaN) transistors are becoming more common in power electronics. This thesis describes how they can be used to improve solar generators by improving the inverter that they contain. The benefits of using GaN in an inverter include higher efficiency, higher switching speeds, and the ability to reduce the size of some inverter components. The full-bridge inverter topology was chosen for this inverter because of its favorable high-frequency switching characteristics. Using a full-bridge GaN-based inverter evaluation board from Transphorm, Inc., a PI control scheme was successfully designed for this inverter using the simulation software PSIM. This control scheme performed satisfactorily when tested in the inverter showing that PSIM can be a useful design tool for high-frequency GaN-based inverters.masters, M.S., Electrical and Computer Engineering -- University of Idaho - College of Graduate Studies, 2020-0
