Abstract

Patente de Invenção:<B>"INDUTOR"<D>. Esta invenção refere-se a um indutor incluindo uma barra condutora alongada (10 de seção transversal retangular, pelo menos parte da barra sendo circundada por uma luva (20) que proporciona um percurso de condução substancialmente não elétrico através da luva em direção contrária da barra condutora. A referida luva (10) concentra as linhas de fluxo magnético na luva. A vantagem do referido indutor é que em altas freq³ências (por exemplo acima de 100Hz) o efeito do "efeito de pele" é reduzido enquanto em freq³ência baixas, mas correntes altas o estresse no indutor é também reduzido.Invention Patent: <B> "INDUCTOR" <D>. This invention relates to an inductor including an elongated conductive bar (10 of rectangular cross section, at least part of the bar being surrounded by a sleeve (20) which provides a substantially non-electrical conduction path through the sleeve in the opposite direction of the bar The glove (10) concentrates the magnetic flux lines in the glove.The advantage of the said inductor is that at high frequencies (for example above 100Hz) the effect of the "skin effect" is reduced while at low frequencies, but high currents the stress on the inductor is also reduced.
