Abstract
CIRCUITO DE CORREçãO DE FATOR DE POTêNCIA DE AMPLIFICAçãO. A presente invenção se refere a um circuito de correção de fator de potência de amplificação utilizando realimentação de potência capaz de fornecer de uma forma estável a fonte de potência à carga pelo corrigir um fator de potência, com o que a potência é realimentada em uma corrente de alta freq³ência utilizando um enrolamento auxiliar a ser incluído em um transformador SMPS. O circuito inclui um dispositivo de retificação para retificar uma voltagem de CA alimentada como entrada, um transformador de indução, tendo um primeiro enrolamento de indução conectado ao dispositivo de retificação e um segundo enrolamento de indução. para acumular uma energia magnética, um transformador SMPS tendo um enrolamento primário conectado ao primeiro enrolamento de indução do transformador de indução e um enrolamento auxiliar conectado ao segundo enrolamento de indução do transformador de indução, o enrolamento auxiliar gerando uma voltagem tendo uma primeira fase oposta àquela da voltagem aplicada ao enrolamento primário, um dispositivo de realimentação de potência conectando em um laço fechado o enrolamento auxiliar do transformador SMPS e o segundo enrolamento de indução para realimentar a energia magnética acumulada no enrolamento auxiliar, e um dispositivo de controle de chaveamento conectado ao enrolamento primário do transformador SMPS, para controlar a operação de chaveamento do transformador SMPS.
