Abstract

Procedimiento y dispositivo para la alimentación de un carga resistiva con corriente alterna bajo tensiones diferentes, cuyo procedimiento para la alimentación directa con corriente alterna suministrada indistintamente bajo una u otra de dos tensiones de cualquier relación de una carga esencialmente resistiva tal como un elemento de calentamiento incorporado en un aparato electrodoméstico, se caracteriza porque consiste esencialmente en impedir selectivamente por conmutación eléctrica mandada en función del valor de la tensión de alimentación , el paso de al menos ciertas alternancias de corriente en por lo menos una fracción determinada de la carga, de manera que la potencia eléctrica disipada sea sensiblemente la misma para los dos valores de la tensión.
