Abstract
Patente de Invenção: <B>"BALASTRO ELETRôNICO PARA PELO MENOS UMA LâMPADA DE DESCARGA DE BAIXA PRESSãO"<D>. Um balastro eletrônico para uma lâmpada de descarga de baixa pressão (LA), contém um inversor que é alimentado com voltagem direta (U~ BUS~) e a cujá saída está conectada com um circuito de carga contendo contatos terminais para a lâmpada (LA), um transformador de aquecimento que possui um enrolamento primário (Tp), que está conectado com a saída do inversor e um respectivo enrolamento secundário (Ts1, Ts2), que está localizado em um circuito de aquecimento com uma bobina (W1, W2), para aquecer cada um dos eletrodos da lâmpada (LA) e uma disposição de circuito em série que está conectada em paralelo com o circuito de carga e que contém o enrolamento primário (Tp) do transformador de aquecimento e uma disposição de chave eletrônica (S3, S4). Para o propósito de identificar o tipo da lâmpada e o estado da lâmpada, as correntes em um dos dois circuitos de aquecimento e no enrolamento primário (TP) do transformador de aquecimento são medidas e avaliadas.
