<p>The circuit comprises: - an input (1) for connection to a low-tension supply (VS), - a storage coil (L1) for storing energy delivered by the supply (VB), and - electronic switching devices (SW1, SW2, SWi) for controlling the connection between the input (1), the storage coil (L1) and each of the loads (Li) in a predetermined manner to achieve a rapid transfer of current to each of the loads selectively, - a capacitor (C) situated in parallel with the branch circuits containing the loads (L1) and connected to the coil (L1) and the electronic switching devices (SW1, SW2, SWi), and - an electronic control unit (ECU) for piloting the electronic switching devices (SW1, SW2, SWi) according to a first operative mode in which, to transfer current to one of the loads (Li), the switching devices cause in succession, after the connection of the storage coil (L1) to the supply (VB): the connection of the storage coil (L1) to the capacitor (C) so as to form a resonant circuit, and then the discharge of the resonant circuit (L1, C) into the load (Li).</p> |
