Filtro ativo de potência trifásico paralelo comandado para várias funções aspectos teóricos e práticos e reator eletrônico alto FP : contribuições a otimização da qualidade de energia

Abstract

This work constitutes an important contribution to the study (analysis, design and practical implementation) of one of the types active power conditioners mentioned at technical literature, as three-phase shunt active power filter. Besides the several theoretical and practical aspects of this structure functioning as active power filter, it is emphasized that the control system employed makes possible to drive such structure to perform different functions, such as pre-regulator Boost converter and interface between CC energy alternative source and the power system. These two functions can be obtained separately or together, even with the function of shunt active filter. During the development of the works there was also a direct participation in another work, resulting in the presentation of a proposal of an electronic ballast with high power factor and low voltage stress. Besides, it was contributed to the presentation of a proposal of a maximum power point tracker system of a photovoltaic set. A brief description of this work is presented in appendix.
