This article presents the first kW-Class, 3-phase GaN-based inverter. Hard-switched at 100-kHz PWM, its heart is a 6-in-1 power module with 600-V GaN power HEMTs, achieving a new efficiency of 98.5%, a more than 2% improvement.
[pdf] The Canadian Solar 3-Phase 6kW Inverter is a high-efficiency, grid-tied inverter designed for residential and small commercial solar systems. It provides reliable power conversion, ensuring optimal energy harvesting and seamless grid integration.
[pdf] 3-phase string inverters perform power conversion on series-connected photovoltaic panels. Usually, these inverters are rated around a few kilowatts up to 350 kW. In general, most inverter designs are transformerless or non-isolated. String inverters typically rely on two-stage power conversion.
