Abstract

ALIMENTAçãO PULSADA EM ALTA FREQüêNCIA DAS LáMPADAS DE DESCARGA descreve conversores eletrónicos para lâmpadas de descarga com estabilização da corrente pulsada em alta freqüência. Utiliza-se um inversor de tensão ou em ponte completa com o controle por valores de pico da corrente, ou em meia ponte utilizando um elemento capacitivo. Esses conversores apresentam uma redução expressiva no volume do circuito de potência, em virtude da retirada do elemento magnético; permitem implementar a variação da intensidade luminosa da lâmpada (dimerização), bem como variar a freqüência dos pulsos numa ampla faixa de freqüência, evitando o aparecimento da ressonância acústica; ainda, permitem uma variação da potência em baixa freqüência, com a finalidade de melhorar as características calorimétricas da luz emitida por alguns tipos de lâmpadas de descarga, como a de vapor de sódio de alta pressão. os conversores apresentam uma redução expressiva no volume do circuito de potência, em virtude da retirada do elemento magnético, sendo tanto mais atrativos quanto maior for a potência da lâmpada.
