Abstract
"LASTRO RESSONANTE EM PARALELO ALIMENTADO COM CORRENTE". Um circuito para o suprimento de voltagem AC e corrente para uma lâmpada de descarga gasosa, quando da aplicação de voltagem DC e corrente, o circuito compreendendo: um transportador, que inclui um primeiro e um segundo enrolamentos primários; um primeiro meio de capacitância, acoplado através dos enrolamentos primários, para definir um circuito ressonante; uma fonte de corrente de partida acoplada a um terminal de acionamento; um primeiro e um segundo transistores acoplados ao terminal de acionamento; pelo menos um enrolamento de acionamento acoplado em uma extremidade ao terminal de acionamento e acoplado na outra extremidade à base de um dos transistores; e um primeiro e um segundo dispositivos de bloqueio de corrente, em uma montagem, um diodo e, em uma outra montagem, um transistor, cada dispositivo de bloqueio de corrente configurado de modo a impedir que uma corrente flua para o elemento emissor de um dos transistores. Adicionalmente, o circuito compreende um meio para estabelecer um fluxo de corrente constante entre os terminais de base dos transistores, suficiente para manter o circuito em um modo oscilante, o meio tendo um indutor linear, um resistor e pelo menos um diodo. Em uma montagem, o circuito tem um enrolamento de acionamento acoplado ao elemento de base do meio de chaveamento de primeiro transistor, e uma combinação em paralelo de um segundo meio de capacitância e um segundo meio de resistor acoplado ao elemento de base do meio de chaveamento de segundo transistor.
