Elevada Freqüência de Operação, Modelo de Lâmpada Fluorescente, Operação em Regime-Permanente, Pré-Aquecimento, Reatores Eletrônicos, Temperatura dos Eletrodos da LâmpadaAbstract
Este artigo apresenta uma nova metodologia para o projeto e ajuste de reatores eletrônicos para lâmpadas fluorescentes de cátodo quente. O clássico inversor Half-Bridge série-ressonante com carga em paralelo compõe o estágio de potência analisado neste artigo. De acordo com a metodologia proposta neste artigo, é possível estabelecer pontos de operação apropriados para a manutenção em níveis recomendados da temperatura dos eletrodos das lâmpadas, durante o pré-aquecimento e a operação em regime permanente.
