Abstract

CIRCUITO DE CONTROLE E MéTODO PARA CONTROLAR A VOLTAGEM DE SAìDA E/OU A CORRENTE DE SAìDA EM UMA FONTE DE ALIMENTAçãO DE COMUTAçãO CONTROLADA PELO LADO PRIMáRIO. A presente invenção refere-se a um circuito para o controle da corrente e da voltagem em uma fonte de alimentação de comutação controlado do lado primário, a qual compreende um transformador com um enrolamento principal de lado primário e de lado secundário, em que os pulsos de energia são transmitidos do lado primário para o lado secundário. Além disso, uma chave do lado primário liga e desliga uma corrente primária através do enrolamento principal do lado primário. Um comparador de corrente primária determina o tempo de desligamento da chave, dependendo da corrente primária. Para reduzir a dependência de carga da voltagem de saída, a variável de controle é amplificada de modo variável por uma rede de retorno, e adicionalmente a variável de controle é reduzida, dependendo da carga de saída através de uma rede de correção. Para reduzir o ruído gerado pelas transmissões de pulso rico em energia em baixas freqüências e a ondulação da voltagem de saída, a variável de controle é retornada ao comparador de corrente primária, de uma maneira tal que a duração pela qual a corrente primária flui através do enrolamento principal do lado primário é reduzida de modo diferente. Para reduzir a susceptibilidade de talha ao determinar o tempo de ligação, Uma voltagem comparadora, que depende da variável de controle, é gerada como referência.
