Abstract

CIRCUITO DE COMPENSAçãO E MéTODO DE OPERAçãO DO MESMO. Descreve-se um circuito de compensação e um método para operar o mesmo que minimiza a distorção de quadro. O circuito de compensação inclui um capacitor principal e uma pluralidade de sub-capacitores para compensar a distorção de quadro, um controlador que provê sinais de controle tendo diferentes ciclos de trabalho, e uma pluralidade de chaves recebendo cada um dos sinais de controle de chaveamento e trocando cada conexão (ou caminho) entre o capacitor principal e os sub-capacitores conforme os sinais de controle de chaveamento recebidos.
