Abstract

La invencion se refiere a un circuito de regulacion de frecuencia para suministrar pulsos de reloj, dependiendo del gasto de corriente a un arreglo de circuito. Ese circuito de regulacion de frecuencia comprende un dispositivo medidor de corriente ( 2 ) para medir el consumo de corriente momentaneo del arreglo de circuito (1), un circuito de suministro de pulsos de reloj controlable (4) que puede conectarse a una entrada de pulso de reloj del arreglo de circuito (1) y un dispositivo de control ( 3 ) para controlar el circuito de suministro de pulsos de reloj (4) a base del gasto medido de corriente. Un aumento en el consumo de corriente del arreglo del circuito ocasiona una reduccion en la frecuencia de los pulsos de reloj en la salida (6) del circuito de suministro de pulsos de reloj (4). El circuito asegura que un maximo de consumo aceptable de corriente no se excedera, permitiendo, al mismo tiempo, que exista la maxima potencia en el circuito debido a un maximo de frecuencia de pulsos de reloj.
