Abstract
dispositivo magnético integrado, circuito de conversão de potência, carregador, e veículo elétrico. este pedido fornece um dispositivo magnético integrado, um circuito de conversão de potência, um carregador, e um veículo elétrico, e pertence ao campo das tecnologias de eletrônica de potência. o dispositivo magnético integrado inclui um núcleo magnético, um primeiro enrolamento de transformador, e um segundo enrolamento de transformador, em que o primeiro enrolamento de transformador e o segundo enrolamento de transformador são separados e enrolados, e um primeiro entreferro é formado na separação. uma linha magnética pode passar através do primeiro entreferro para formar indutância de dispersão, e a indutância de dispersão pode ser equivalente à indutância ressonante no circuito de conversão de potência. portanto, não há necessidade de dispor separadamente um enrolamento de indutor no dispositivo magnético integrado. isso efetivamente reduz um volume e um peso do dispositivo magnético integrado. além disso, o circuito de conversão de potência que usa o dispositivo magnético integrado também tem um volume relativamente pequeno e densidade de potência relativamente alta.
