A power inverter, inverter, or invertor is a device or circuitry that changes (DC) to (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of which were originally large electromechanical devices converting AC to DC. Inverter signal outputs that aim to replicate mains power are commonly 50 or 60 Hz at 120 or 240 VAC to match standard power line frequencies and voltage. In cases where the output needs to be further processed or stepped up, the output frequency may be much higher for transformer efficiencies.
[pdf] 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.
