Abstract

<B>"ENROLAMENTO EM TRANSFORMADOR OU EM INDUTOR"<D>. A presente invenção divulga um transformador ou indutor de energia. O enrolamento (31) do transformador/indutor é feito de um condutor flexível (38) tendo campo elétrico que contém meios que forçam o campo elétrico, devido à corrente elétrica no enrolamento (31) a ser contido dentro da camada isolante do condutor flexível (38). A espessura da camada isolante do condutor flexível (38) é adotada de tal modo a tornar a tensão elétrica (33) constante através da extensão do enrolamento. A área de seção transversal da camada isolante do condutor flexível (38) é portanto otimizada, proporcionando um projeto de um transformador/indutor com um alto fator de espaço.<B> "WINDING IN TRANSFORMER OR INDUCTOR" <D>. The present invention discloses a power transformer or inductor. The winding (31) of the transformer / inductor is made of a flexible conductor (38) having an electric field that contains means that force the electric field, due to the electric current in the winding (31) to be contained within the insulating layer of the flexible conductor ( 38). The thickness of the insulating layer of the flexible conductor (38) is adopted in such a way as to make the electrical voltage (33) constant through the extension of the winding. The cross-sectional area of the insulating layer of the flexible conductor (38) is therefore optimized, providing a transformer / inductor design with a high space factor.
