Abstract

1/1 resumo “transformador planar” as modalidades fornecem uma placa de circuito impresso de multicamadas, pcb, para fornecer primeiros enrolamentos para um primeiro lado de um transformador magnético planar e segundos enrolamentos para um segundo lado do transformador magnético planar, o pcb compreendendo: uma pluralidade de camadas condutoras configuradas para fornecer os primeiros enrolamentos; uma pluralidade de camadas condutoras configuradas para fornecer os segundos enrolamentos; e uma pluralidade de camadas de um material de isolamento; em que cada camada de material de isolamento é disposta entre duas camadas condutoras de modo a fornecer isolamento elétrico entre as duas camadas condutoras; e um grupo de duas ou mais camadas condutoras adjacentes são todas camadas condutoras dos primeiros enrolamentos e são todas dispostas entre duas camadas condutoras dos segundos enrolamentos, em que a espessura do material de isolamento entre o grupo de camadas condutoras adjacentes dos primeiros enrolamentos é menor que a espessura do material de isolamento entre uma camada condutora dos segundos enrolamentos e uma camada condutora dos primeiros enrolamentos. vantajosamente, um pcb com uma altura mais baixa que realizável com desenhos de transformador magnético planar totalmente intercalados conhecidos é fornecido. a altura reduzida melhora a condutividade térmica do pcb, vazamento de fluxo é reduzido e bom acoplamento magnético entre os lados primário e secundário é mantido.
