This article proposes a 10kW string inverter based on GaN field-effect transistors (FETs). We will also explore the benefits of GaN and highlight the advantages of building such a system for residential solar applications.
[pdf] Abstract— This paper introduces a new dc-dc converter suitable for operation at very high frequencies under on-off control. The converter power stage is based on a resonant inverter (the Φ2 inverter) providing low switch voltage stress and fast settling time.
[pdf] All L1 series inverters feature dual MPPT trackers with a wide operating voltage range of 120V to 600V, allowing for flexible system design and the ability to handle short strings of just 4 panels.
