Conversores estáticos operando em alta tensão aplicados em filtragem eletrostática

Abstract

This work concern to the basic fundamentals and theory of electrostatic precipitation, showing the characteristics and advantages of use of this air cleaning technique. Comparing the geometries of available equipments, it proposes changes in the mechanical structure of a commercial filter, in order to implement an electronic control system.A high-voltage controlled converter is presented and proposed separately to both ionization and dust collecting stages. The new converter allows to act independently in the ionization and in the collection control.The experimental results obtained with the proposed converters are presented comparatively to the original structure find in the electrostatic precipitator in study.
