New series active power filter for small non-linear loads simulation and experimental work

This paper explains the behaviors of the new version f the series active power filter based on high input power factor and low input harmonics. The filter is designed to meet the requirements of voltage-current sourced harmonic loads it is based on a load current estimation of the active power filter sensing the load current. The proposed filters can improve the distortion of a small a non-linear loads power. In addition, it can suppress the harmonic current and compensate for the reactive power at the float charge mode. The experimental results verify that the proposed filters have the expected performance.
