Abstract
A method for controlling the temperature of an electric propulsion system. The electric propulsion system includes a discharge channel, an anode, a cathode, an injection system and a magnetic circuit. The injection system injects propellant gas into the discharge channel and the magnetic circuit has at least one magnetic winding to generate a magnetic field in the discharge channel. The temperature at a reference thermal point of the electric propulsion system is determined. The electric propulsion system is heated by the Joule effect by applying a current to the magnetic circuit when the determined temperature is below a minimum temperature predetermined during a stop phase of the electric propulsion system.
