Development of a high-efficiency solar micro-inverter

Abstract

In typical solar power installations, multiple modules are connected to the grid through a single high-power inverter. However, an alternative approach is to connect each solar module directly to the grid through a micro-inverter. This approach makes the system robust to single module failures and results in better power tracking. This project involves the development of a next generation micro-inverter architecture, including the design, assembly, and testing of a prototype converter. The topology involves a full bridge resonant inverter at the input, which supplies high-frequency current through a transformer to a cycloconverter at the output.
