Abstract

"TRANSFORMADOR COM MúLTIPLAS CAMADAS POSSUINDO CONEXãO ELéTRICA EM UM NúCLEO MAGNéTICO". Trata-se de um método, aparelho e artigo de fabricação para um transformador com múltiplas camadas que inclui uma pluralidade de camadas (168 até 174) possuindo uma área de núcleo magnético (114) disposta em cada uma das camadas formando um núcleo magnético do transformador possuindo um enrolamento primário (126, 128) disposto em pelo menos uma das camadas e um enrolamento secundário (178, 180) disposto em pelo menos uma das camadas. Uma pluralidade de vias de interconexão (130) conectam o enrolamento primário entre as camadas e uma segunda pluralidade de vias de interconexão (130) conectam o enrolamento secundário entre as camadas. As vias de interconexão são dispostas próximas a um centro do núcleo magnético do transformador, desse modo reduzindo o volume, tamanho, peso e custo geral de um transformador enquanto indo de encontro aos regulamentos de requerimentos de segurança de isolamento.
