DISPOSITIF ELECTRIQUE D'ENTRAINEMENT D'UN EQUIPEMENT MECANIQUE ET PROCEDE ASSOCIE

摘要

The device has an inverter whose H bridge structure comprises four switching elements that are distributed over two branches connecting two terminals (21) of the H bridge structure for each phase of an alternating current electric motor i.e. three-phase motor. One of the terminals of the H bridge structure is configured to supply a winding (23) of the phase of the motor. An energy storage unit i.e. supercondenser (7), is connected to the motor via a mid point (25) of the winding and to a terminal of the H bridge structure for supplying the winding. The switching elements comprise a transistor such as insulated gate bipolar transistor, and a diode that are connected in parallel. An INDEPENDENT CLAIM is also included for a method for retrieving electrical energy produced by an electric motor of a motor vehicle.
