Abstract
MéTODO E ELEMENTO PARA CONTROLE DO FATOR DE POTêNCIA DE UMA LINHA DE SUPRIMENTO DE ENERGIA A presente invenção descreve um método para controlar o fator de potência de uma linha de suprimento de energia, o método utilizando um elemento de controle conectado à linha de suprimento de energia. Vantajosamente, de acordo com a invenção, o controle do fator de potência é executado mediante modulação do tempo de condução de transistor bipolar (TB1) compreendido no elemento de controle e mediante regulação dessa modulação do tempo de condução através de acionamento de realimentação de um terminal de controle (B1), do transistor bipolar (TB1). A invenção também descreve um circuito para controlar o fator de potência de uma linha de suprimento de energia, do tipo que compreende um primeiro e segundo terminais de entrada (I1, I2) conectados à linha de suprimento de energia, assim como, primeiro e segundo terminais de saída (01, 02) conectados a uma carga. Vantajosamente, de acordo com a invenção, o circuito de controle compreende um elemento de controle do fator de potência (15) e um bloco de regulação (16) conectado por realimentação ao mesmo. O elemento de controle de fator de potência (15), compreende um transistor bipolar (TB1), inserido entre os primeiro e segundo terminais de entrada (I1, I2) e apresenta um terminal de controle (B1) conectado a um terminal de saída (04) do bloco de regulação (16), o qual, por sua vez, compreende pelo menos um transistor complementar (02) que apresenta um terminal de condução conectado ao terminal de saída (04), para reduzir as cargas no terminal de controle (B1) do transistor bipolar (TB1).
