Abstract

"COMUNICAçãO DIGITAL SOBRE LINHA DE ENERGIA DE 28 VCC". A presente invenção refere-se a uma interface de modem de linha de energia que inclui um modem que modula um sinal RF com dados digitais e desmodula um sinal RF para recuperar dados digitais. Um filtro é conectado ao modem e a uma linha de energia CC que fornece energia para um fornecimento de energia local. O filtro acopla os sinais RF a partir do modem para a linha de energia CC e filtra os sinais RF do fornecimento de energia local. O filtro inclui uma primeira indutância conectada a um lado quente da linha de energia CC; uma segunda indutância conectada em série com a primeira indutância e conectada ao fornecimento de energia local; e uma capacitância com uma primeira placa conectada entre a primeira indutância e a segunda indutância, e uma segunda placa conectada ao modem, de modo que o sinal RF é passado entre o modem e a linha de energia CC.
