To alleviate the power quality problem with the alternating current (ac) mains in an ac–direct current (dc) power supply delivering to a nonlinear load, this project report describes the design, modeling, and development of a passive shunt filter and a shunt hybrid power filter (SHPF). The power filter consists of an active power filter and a passive shunt filter connected in series. The first step was to design a passive filter capable of eliminating harmonic distortion. By addressing concerns like fixed compensating features and the resonance problem, SHPF is an effort to improve upon passive filters. Simulations of a typical distribution system with an SHPF were performed to validate the study results presented. To demonstrate how the harmonic extraction circuit influences the SHPF’s harmonic compensation characteristic, the harmonic contents of the source current have been calculated and compared for different scenarios. This was done to demonstrate the effect of the circuit on the harmonic contents. Shunt passive filter, SHPF, harmonic correction, and modeling are some of the keywords here.
