Abstract:
1. A method of controlling a machine including at least one inductive coil, the inductive coil being connected to a primary electricity power supply network via a control circuit comprising, between a connection point of the coil under consideration and terminals of the primary network, at least one half-bridge of a variator adapted to controlling said machine, said half-bridge being formed by first and second controlled switches, the first and second switches each being capable of occupying an ON or an OFF electrical state, the method comprising: connecting the connection point of the coil to at least one third controlled switch capable of occupying an electrical OFF state or an electrical ON state, the third switch constituting a bypass switch connected to at least one secondary electrical power supply network; and associating the electrical state of the third switch with that of the half-bridge in such a manner that the electrical energy stored in the inductive coil of the machine is retransmitted to the main network and/or to the secondary network.
