This article proposes a 10kW string inverter based on GaN field-effect transistors (FETs). We will also explore the benefits of GaN and highlight the advantages of building such a system for residential solar applications.
[pdf] Essentially, a grid-following inverter works as a current source that synchronizes its output with the grid voltage and frequency and injects or absorbs active or reactive power by controlling its output current.
[pdf] This paper presents a comprehensive analysis of single-phase grid-connected inverter technology, covering fundamental operating principles, advanced control strategies, grid integration requirements, and power quality considerations.
