1.6-kW, Bidirectional Micro Inverter Based on GaN Reference Design (Rev. A) This reference design implements a four-channel 1.6-kW single-phase bidirectional micro inverter based on GaN. The reference design supports four identical channels with up to 60 V and ±14 A on the DC side.
However, the total power loss (Ptotal = Pin - Pout) does not include the gate drive power in the MOSFET. If the 4th generation SiC MOSFETs are used, the efficiency is improved over nearly an entire load range. At 5 kW, the loss is reduced by 10.13 W compared with the 3rd generation SiC MOSFETs.
In residential use cases, micro inverters present a good trade-off in terms of costs and efficiency together with a simple end-user installation. Conversely, the energy storage system becomes a challenge in existing micro inverters due to the lack of a bidirectional converter in this end-equipment.
