ABSTRACT:
A method of controlling a machine including at least one inductive coil (n), the inductive coil being connected to a primary electricity power supply network (RP) via a control circuit comprising, between a connection point (A) of the coil (n) in question and terminals of the primary network (RP), at least one half-bridge of a variator adapted to controlling said machine, the half-bridge being formed by first and second controlled switches (T+n, T−n). In the method, connection point (A) of said coil (n) is connected to at least one third controlled switch (Tn-x), the third switch (Tn-x) constituting a bypass switch connected to at least one secondary electricity power supply network (Rx), and the electrical state of the third switch (Tn-x) is associated with that of the half-bridge.
