چکیده
This paper presents a shunt hybrid active power filter application mainly for current harmonic elimination and fixed reactive power compensation. The proposed system consists of a small rated voltage source active power filter and a series of LC passive filter connected to each phase. Besides, no additional switching filter is required for the current ripples. Effectiveness of the system is confirmed by the experimental results obtained from a laboratory prototype.
