Three-Phase Four-Wire Hybrid Active Power Filter for Mitigating Harmonic Problems Caused by CFLs Lamps based on a Shunt Active Power Filter SAPF in Parallel with a Passive Filter

WSEAS TRANSACTIONS ON CIRCUITS AND SYSTEMS
The widespread integration of nonlinear loads across industrial, commercial, and residential settings has significantly exacerbated power quality issues within contemporary power distribution systems. An example of such nonlinear loads is the prevalent use of compact fluorescent lamps (CFLs), intended as replacements for incandescent lamps (ILs).
