3.6kW, GaN-based single-phase string inverter reference design
TIDA-011008
概覽
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.
特點
- Power stage with high power density makes solar inverters lighter and easier to install
- High switching frequency of 100kHz and high-efficiency design
- Cost-optimized with MCU GND referenced to VDC-, allows use of nonisolated drive on all GaN devices connected to VDC-
- Cost-optimized full-bridge topology: Implements an H-bridge bipolar modulation scheme to maintain low control complexity and robust grid injection
- Excellent power quality: Achieves less than 1.23% current THD with a grid emulator under high load conditions
- Wireless connectivity: Features the SimpleLink™ dual-band wireless MCU (CC3551E) for integrated Wi-Fi 6 and BLE communication
