Abstract

resumo “sistema autotransformador para reduzir a distorção harmônica total” descreve-se um aparelho e um método para reduzir a distorção harmônica total de entrada para um sistema de auto-transformador de 24 pulsos e o próprio sistema de auto-transformador. o sistema de autotransformador de 24 pulsos está configurado para receber uma entrada de uma primeira tensão e produzir uma tensão de saída de uma segunda tensão. o sistema inclui um par de autotransformadores acoplados a uma fonte de energia ac. um enrolamento de cada fase do primeiro autotransformador tem uma relação de enrolamentos para efetuar uma diminuição na tensão através do dito enrolamento ao longo de um valor de tensão simétrica e um segundo enrolamento de cada fase do primeiro autotransformador tem uma relação de enrolamentos para efetuar uma diminuição na tensão através do referido enrolamento sobre um valor simétrico de tensão, reduzindo assim a distorção harmônica total (thd) na corrente de entrada para o sistema de bloqueio sem um transformador homopolar.
