Abstract (en)

[origin: WO2007057925A1] The device includes at least one vaporization source (31) heated by Joule effect due to the passage of an electric current and a powering system of said at least one source, with a control circuit (101) of the power supplied to the source. This circuit includes an inverter, which supplies an essentially sinusoidal voltage to the source (31), the power being regulated by acting on the amplitude of the voltage supplied to the source.
