Due to the non-renewable nature of fossil fuels, the global energy market demand continues to be tight, and there is an urgent need for a new renewable energy source to fill the gap. In this context, photovoltaic power generation has received widespread attention as a new energy generation method characterized by green and sustainable development. In the PV power generation device, the inverter as a kind of alternating current (AC) and direct current (DC) conversion device, plays an important role in the power supply quality and power generation efficiency. Therefore, the research and analysis of inverter is of great significance. This thesis takes the single-phase full-bridge inverter system with RL - type filter circuit as the research object, completes the overall design of the inverter system, and carries out functional debugging and performance testing of the system. The main contents of the thesis are summarized as follows:

According to the technical specifications of the inverter system, the topology of the power unit is selected, and then the overall design scheme of the inverter is completed, the selection of the main components such as power switching tubes is determined, and then the power loss of the inverter is calculated through modeling and simulation.
