Diseño e implementación de un filtro pasivo shunt multietapa resonante para la mitigación de armónicos producidos por una carga no lineal.

Abstract

This research content one of the solutions that exist to solve problems related to current waveform distortion due to effect produced by the non-linear load operation, which also affects to voltage waveform. At first, the harmonic content generation related to load was researched and an electrical system with a 200 % THD value was achieved. To reduce this distortion, a system filtering based on the passive elements operation was researched and implemented; in this way the shunt resonance to contaminated electrical system was obtained to generate a low impedance path to 3rd, 5thand 7th harmonic frequencies order. The research methodology implies the programming, simulation, implementation and experimental tests associated with the electrical system previously created. Therefore an important THD reduction was obtained because its value fell to 50 %.
