Scientists use series active filter to improve power quality of grid-tied PV
Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The filter reduces total harmonic distortion in voltage and current waves at the inverter output.
