<p>Simple and economical device allowing the recovery of energy stored by the grid-leak inductances of the electrical machine connected to the thyratron inverter. According to the invention, the device comprises a transformer of which the primary winding (13), in series with at least a switching transistor (14) controlled by the logic (5) of the thyratron inverter, is connected between the terminals of the capacitor (12) in which the energy to be recovered is transferred, and of which the secondary winding (15) is arranged in series with one of the terminals of the direct current source (4) and the corresponding input of said thyratron inverter. Application: control of electric motors. </p> |
