Abstract

"LASTRO ELETRôNICO COM CONVERSOR DE REFORçO". Onde o lastro eletrônico (10) para cargas de lâmpadas de gás, tais como lâmpadas ionizadas, que inclui uma correção de fator de potência de reforço (30) utilizada para corrigir o fator de potência e minimizar a distorção harmônica total. O reforço (30) inclui um indutor (31) que armazena periodicamente e descarrega sua voltagem resultante em um capacitor de carga (34) através de um diodo de passagem opcional (32) conectado em paralelo a uma chave eletrônica (51), utilizando-se o oscilador (40) que é aplicado à carga. A adição do diodo de passagem (32) reduz a distorção harmônica total. O indutor (31) é selecionado em combinação com o restante do circuito, de forma a nunca atingir saturação. O indutor (31) carrega periodicamente o capacitor de carga (21) acima (o dobro) do pico de voltagem que é fornecido por uma fonte contínua retificada de voltagem direta. A carga de descarga de alta intensidade (80) é conectada a um circuito ressonante apropriado (60). O indutor de carga (31), bem como os elementos do circuito ressonante (60) e elementos de orientação do oscilador incluem dispositivos que permitem ao usuário selecionar valores diferentes, de forma a afetar a freqüência ressonante.
