Abstract

La invencion se refiere a un arreglo de circuito para operar una lámpara (LA) de descarga con una corriente de alta frecuencia que comprende: - terminales (K1, K2) de entrada para conectarse a una fuente de voltaje de abastecimiento de baja frecuencia, - mecanismos (D1-D4) rectificadores acoplados a dichas terminales de entrada para rectificar dicho voltaje de abastecimiento de baja frecuencia, y - mecanismos (Q1, Q2, DC) inversores para derivar dichos primeros mecanismos capacitivos para generar la corriente de alta frecuencia. De acuerdo con la invencion, el arreglo de circuito incorpora dos lazos de retroalimentacion de energía para alimentar la energía de nuevo a una terminal de salida del puente rectificador. Como resultado, el arreglo de circuito tiene una configuracion relativamente sencilla, provoca solo una cantidad muy limitada de distorsion armonica y puede ser hecho con componentes relativamente baratos y sencillos.
