Abstract

La presente invención se refiere a un balasto sin transformador para una lámpara de descarga no gaseosa es revelado. El balasto consta de: un rectificador, un filtro para la salida del rectificador, un dividor de voltaje para la salida del filtro, un conmutador electrónico que modula por ancho de pulso y por frecuencia la salida del filtro para dar energía a la lámpara cuando la lámpara esta encendida, un controlador que controla el conmutador electrónico sensible a las variaciones en impedancia de lámpara y a las variacioneds en la salida del divisor de voltaje (y por tanto de variaciones en el voltaje de la linea); un oscilador que genera una salida durante un periodo predeterminado de tiempo hasta después que la lámpara está encendida; y un amplificador que recibe y amplifica la salida del oscilador para dar energía a la lámpara cuando la lámpara no está encendida.The present invention relates to a transformerless ballast for a non-gas discharge lamp is disclosed. The ballast consists of: a rectifier, a filter for the rectifier output, a voltage divider for the filter output, an electronic commutator that modulates by pulse width and by frequency the filter output to power the lamp when the lamp is on, a controller that controls the electronic switch sensitive to variations in lamp impedance and variations in the output of the voltage divider (and therefore variations in line voltage); an oscillator that generates an output for a predetermined period of time until after the lamp is on; and an amplifier that receives and amplifies the output of the oscillator to power the lamp when the lamp is not lit.
