TIDA-010933
1.6kW, bidirectional micro inverter based on GaN reference design
TIDA-010933
Overview
This reference design shows a four-input bidirectional 1.6kW GaN-based microinverter with energy storage capability.
Features
- High-power density
- High-switching frequency to enable small passive EMI filter components
- Any channel can either operate as PV input or 48V battery storage
- Single chip controller with one C2000 MCU (DC/AC, DC/DC, MPPT)
- Good common mode isolation with Isolated DC/DC topology
- Low overall system solution cost
