Abstract

"SISTEMA DE SUPRIMENTO DE ENERGIA COM OPERAçãO EM PARALELO DE INVERSORES MONOFáSICOS OU POLIFáSICOS". Um sistema de suprimento de energia composto por inversores conectados em paralelo, aplicável principalmente em fontes ininterruptas de energia, também denominadas NOBREAK ou UPS (Uninterruptible Power Supply). O paralelismo oferece capacidade de ampliação da potência, através da conexão de novos inversores ao sistema e também confiabilidade, já que inversores defeituosos ou necessitando manutenção podem ser retirados do sistema sem interrupção do fornecimento, desde que a capacidade total dos inversores restantes seja igual ou superior à exigida pela carga. No paralelismo, um dos inversores assume o papel de mestre, operando como fonte de tensão, enquanto os demais assumem o papel de escravos, operando como fontes de corrente. Através de um barramento de comunicação entre os inversores, o mestre informa a referência de corrente de cada fase para os escravos. A referência é informada em valor relativo à potência nominal do mestre, permitindo que inversores de diferentes potências façam parte do sistema e que a distribuição da carga seja proporcional à potência nominal de cada inversor.
