Abstract

"TRANSFORMADOR E INDUTOR PARA APLICAçõES DE BAIXA FREQ êNCIA". Um transformador para aplicações de baixa freq³ência de 50 Hz a 1.000 Hz é descrito. O transformador compreende um núcleo possuindo uma simetria cilíndrica ao redor de um eixo principal de revolução. O núcleo e formado de um material de compósito macio magnético isotrópico composto de ferro e resina. Os enrolamentos são encerrados no núcleo magnético e dispostos ao redor de uma coluna central do núcleo magnético e magneticamente acoplados ao núcleo magnético. O núcleo é formado por seções de núcleo. Um indutor para aplicações de baixa freq³ência, CC a 1.000 Hz, de construção similar, também é descrito, o indutor compreendendo um núcleo possuindo uma simetria cilíndrica ao redor de um eixo principal de revolução. O núcleo é formado de material de compósito magnético isotrópico macio composto de ferro e resina. O enrolamento é encerrado no núcleo magnético e disposto ao redor de uma coluna central do núcleo magnético e magneticamente acoplado ao núcleo magnético. O núcleo é formado por seções de núcleo.
