This reference design provides an overview into the implementation of a GaN-based single-phase string inverter. The design consists of one string input, able to handle up to 10 photovoltaic (PV) panels in series. The nominal rated power from string inputs to a single-phase grid connection at 230V is up to 3.6kW. Digital control of the three power stages is executed on a single C2000™ MCU. This board also features a WiFi® communication port to enable easy and remote monitor and control access.
