Abstract

transformador amorfo para fonte de alimentação elétrica esta invenção fornece um transformador amorfo para fonte de alimentação elétrica usando um núcleo magnético formado de um material de liga amorfa, que, comparado com o material de liga amorfa convencional, tem uma menor temperatura de recozimento e um maior nível de propriedades magnéticas. o transformador amorfo para fonte de alimentação elétrica é provido com um núcleo magnético de uma tira fina de uma liga amorfa e um arame de enrolamento. o núcleo de ferro foi recozido em condições tais que a temperatura da parte central do núcleo de ferro durante o recozimento depois da moldagem do núcleo de ferro é 300 a 340 <198>c e o tempo de retenção não é menor que 0,5 hora. adicionalmente, para o núcleo de ferro, a força do campo magnético durante o recozimento depois da moldagem do núcleo de ferro não é menor que 800 a/m.
