Abstract

Un convertidor elevador para un balasto electrónico con graduador de intensidad para activar una lámpara de descarga gaseosa que tiene un mayor intervalo de potencia de salida. El convertidor elevador funciona en el modo de conducción discontinua cuando una intensidad deseada de la lámpara es menor que una primera intensidad de umbral, y funciona en el modo de conducción crítica cuando la intensidad deseada es mayor que una segunda intensidad de umbral. El convertidor elevador comprende un circuito de retardo para introducir una cantidad de retraso en la conducción de corriente a través del convertidor elevador. Un circuito de mando del balasto es operable para activar el circuito de retardo y así controlar el funcionamiento del convertidor elevador en respuesta a la intensidad deseada de la lámpara. El circuito de mando es adicionalmente operable para activar el circuito de retardo con una señal modulada por ancho de pulso a proporcionar múltiples cantidades del retraso en el funcionamiento del convertidor elevador.
