一种抑制单相光伏微逆变器系统线路频率谐波的方法

Single-phase microinverters used in household applications draw pulsating power from its input dc source while delivering ac power output to loads. While this introduces double line frequency harmonics into the dc bus of the microinverters, which lead to poor operational efficiencies of input energy sources (like solar arrays and fuel-cells etc.), it also deteriorates the quality of power fed to a...
