Unified Power Quality Conditioner (UPQC) for harmonic elimination and simultaneous compensation of voltage and current, which improves the power quality offered for other harmonic sensitive loads. UPQC consist of combined series active power

This paper presents a hybrid parallel active filter scheme using small rated square-wave inverters for supply line harmonic current reduction for high power non-linear loads in the range of 1 - 50 MW to meet IEEE 519 harmonic standards.
