Abstract
La presente invención se refiere a un circuito de control de potencia para controlar la potencia para una lámpara de descarga desde un suministro de potencia que incluye una etapa de entrada cd y un interruptor de potencia que cambia selectivamente entre un estado conductivo para psar corriente a través de dicha lámpara y un estado no conductivo, por medio del cual la corriente que pasa a través de dicha lámpara incrementa cuando dicho interruptor está en estado conductivo y disminuye cuando dicho interruptor está en estado no conductivo; comprendiendo dicho circuito de control de potencia: un medio de control de corriente para crear una serie de ciclos de operación (T) que incluyen una primera porción de activación (W) donde dicho interruptor es en forma alternada conductivo y no conductivo en sucesión y una porción en resposo (T-W) en la que dicho interruptor es no conductivo; un medio para detectar la corriente instántanea a través de dicho interruptor de potencia e independiente del paso de dicha corriente a través de dicha lámpara; un medio para crear una primera señal proporcional al promedio de dicha corriente detectada; un medio para crear una segunda señal proporcional a una potencia de punto de ajuste; un medio para crear una señal de error indicativa de la diferencia entre la primera y la segunda señales; y un medio para ajustar el tiempo de la primera porción de activación (W) de dicho ciclo de operación (T) de acuerdo con la señal de error por medio de la cual la potencia de salida de dicho suministro de potencia es continuamente ajustado hacia dicha potencia de punto de ajuste.
