500VA Hybrid filter development for harmonic elimination of a single phase power

초록
Because of the high cost for the active power filter, passive filters have been widly used to absorb harmonic currents of nonlinear loads and can also improve the power factor. They are not often optimal filters because the passive filters are designed with the fixed load conditions. In this paper we proposed the method which only the necessary harmonic filters are operated by detecting the various harmonic current components. By the experimental results using the proposed system for the 500VA rectifier load, we concluded that the researched hybrid filter is cost effective and the performance is better than the passive filter.
