ABSTRACT:
A controller associated with a dissipative electric load controls the level of average power applied to the load by an electric energy distribution network that supplies the dissipative load with a supply voltage. The controller comprises a detector for detecting a predetermined pulse duration modulation signal embedded in the level of the supply voltage provided by the distribution network, and a device for transmitting electric power originating from the distribution network to the load. The device for transmitting comprises a device for reducing the level of average power transmitted to the load, in response to a detection of said pulse duration modulation signal in the level of supply voltage. A decrease of the line voltage level for a given duration of power distribution voltage is initiated in order to control the average power consumption of the loads.
