The Development of the High Efficiency Power Conditioner for Photovoltaic Power Generation by Using an SiC Device

Abstract

This report introduces a 3 phase 3 wire 10kW photovoltaic power conditioner. LINE BACK αⅣthat uses an SiC device as the main circuit switching device. By using the SiC switching device, this power conditioner is able to greatly improve efficiency thus achieving a fanless, self-cooling and sealed structure. Furthermore, LINE BACK αⅣ is also equipped with functions like FRT, Output power control, new-type islanding operation detection that are required for grid stability.
