TIDA-010938
7.2-kW, GaN-based single-phase string inverter with battery energy storage system reference design
TIDA-010938
概述
This reference design is a single phase string Inverter with two string inputs, each able to handle 10PV panels in series and one energy storage system port that can handle batteries stacks from 80V to 500V. The rated power from string inputs to battery storage systems is up to 7.2kW. The configurable AC/DC converter can handle up to 3.6kW into a single phase grid connection at 230V.
特性
- Configurable AC/DC (HERIC, H-Bridge uni- and bi-polar modulation scheme)
- Twice the power density improvement makes solar inverters lighter and easier to install (2.6kW/L)
- Low total losses (<2%) harness more sun and make battery energy storage more efficient
- Help reduce total manufacturing footprint as passives and heatsinks reduce overall size and material use
- Cost optimized with MCU GND referenced to VDC- to allow non-isolated drive on all GaN devices connected to VDC-
