In this paper, APLC(Active Power Line Conditioner) is designed for low consumed power electrical equipment such as communication electronic equipment, computer sever and etc.. Because APLC which is hunted to the mains controls only the elements of harmonics, the designed APLC is very high efficient. Additionally, controller designed with low cost micro-controller and analog circuit has good merit economically. Simulation and experimental results on a prototype verify the feasibility of the proposed scheme.
