摘要

Method and device for feeding a resistive load with alternating current under different voltages, whose method for the direct supply with alternating current supplied indistinctly under one or other of two voltages of any ratio of an essentially resistive load such as a built-in heating element in an electric household appliance, it is characterized in that it consists essentially of selectively preventing, by electrical commutation, as a function of the value of the supply voltage, the passage of at least certain current alternances in at least a certain fraction of the load, so that the electrical power dissipated is substantially the same for the two values of the voltage.
