Filtro ativo paralelo trifásico para sistemas de baixa potência.

Abstract

The present study consists of a three-wired parallel three-phase active power lter project using a Voltage Source Converter (VSC) with the switches control signals implemented by a digital signal processor (DSP) TMS320F2812 to the compensation of the power factor and harmonic currents produced by balanced non-linear loads. The performance of the active lter control depends directly on the strategy adopted. In this work, a comparative study will be made about the active lter control techniques that use the network current measurement or the current measurement of the load and the lter. Experimental and simulation results were proved with an active lter prototype built in the LEIAM.
