Texas Instruments LMG3522R050 | Demoboard TIDA-010933
1.6kW, bidirectional micro inverter based on GaN reference design
Overview
| Topology | Positive to Negative Converter |
| Input voltage | 30-60 V |
| IC revision | DECEMBER 2023 |
Description
This reference design implements a four-channel 1.6-kW single-phase bidirectional micro inverter based onGaN. The reference design supports four identicalchannels with up to 60 V and ±10 A on the DC side.These channels can be connected to photovoltaic(PV) panels or to 48-V Battery Energy StorageSystems (BESS). On the High-Voltage (HV) side, thereference design is connected to a single-phase ACgrid. The reference design has Low-Voltage (LV) andHV sides isolated by means of a bidirectional fixedfrequency CLLLC converter. The control algorithm forthe reference design is implemented in C2000™ MCU.
Features
High-power densityHigh-switching frequency to enable small passive EMI filter componentsAny channel can either operate as PV input or 48V battery storageSingle chip controller with one C2000 MCU (DC/AC, DC/DC, MPPT)Good common mode isolation with Isolated DC/DC topologyLow overall system solution cost
Typical applications
- Micro inverter
