Power Factor Control in Buildings Using Air Conditioners with Built-in Active Filters

Abstract

Air conditioners with built-in active filters have excess distortion compensation capacity during off-season and light-load periods. It was assumed that the excess capacity during these periods could be used to improve the leading power factor. This study investigates the possibility of using the excess distortion compensation capacity in an automatic power factor regulator of an air conditioner with a built-in active filter to improve the leading power factor of the electric system during light-load periods, i.e., off-season.

Based on the analysis and evaluated results, the desired level of control was achieved for the improvement of the power factor.
