The control circuit comprises a source of dc voltage, a first electronic switch, interposed between a first terminal of the voltage source and a corresponding first terminal of the load, a second electronic switch, interposed between the other or second terminal of the load and the other or second terminal of the source, a current recirculation device, including a diode connected between the said first terminal of the load and the other or second terminal of the voltage source to allow a circulation current in the load when the first switch is open, and a control circuit arranged to control the switches in a predetermined manner. The recirculation device further includes a third electronic switch disposed between the first terminal of the load and the other or second terminal of the voltage source, and the control unit is arranged to control this third switch in a synchronous manner, but in phase opposition, in relation to the first switch.
