Electric blanket, with a heating element and with an energy source for it, characterized by understanding: A) a controlled silicon rectifier provided with an anode, a cathode and a control electrode, said anode being connected to a terminal of a power source and said cathode connected to the other terminal of said power source through the heating element of the blanket; B) sensitive means that react to the temperature, arranged below said blanket, to vary the input energy of said control electrode, thus varying the conduction time of said controlled silicon rectifier, therefore, the current that passes by said heating element varies according to the temperature obtained under the blanket.
