摘要

This paper presents a solution based on a new GaN device photovoltaic inverter for grid-connected solar power systems. This PV inverter uses the many advantages of GaN semiconductor devices to convert the solar energy in the PV cell set to the grid or to the end-use of the power equipment by using the latest technologies such as maximum power point tracking and detection and grid connection, which greatly improves the conversion efficiency, in addition to the advantages of clean and efficient.
