An electrical supply holding circuit includes a primary stage and a secondary stage. The primary stage includes a voltage connector connected to a supply network, and a primary winding connected to a voltage converter. The secondary stage includes a secondary winding facing the primary winding, the primary and secondary windings forming two coupled inductances, and a voltage controller to which the secondary winding is connected, the voltage controller being connected to a load and controlling a voltage across the terminals of the load. Directions of the currents flowing through the primary and secondary windings are the reverse of one another, and the voltage converter stops the supply to the primary winding when the supply voltage is less than a threshold voltage and resumes the supply to the primary winding when the supply voltage is greater than a threshold voltage.
