The invention relates to an electric energy exchange system between at least one motor-generator system (MG) and at least one storage member (B) determining a continuous storage voltage between two branches (21, 21') of a bus circuit on which are connected in parallel a DC/DC converter (1), a filtering capacity (2) and a DC/AC converter (C1, C2) connected on at least one motor-generator system (MG). According to the invention, the system includes at least one thyristor (41) connected as a bypass on the positive bus (21) between the storage member (B) and the output of the converter-voltage raiser (1) in order to short-cut said converter (1), and a thyristor (41) priming means based on the required voltage at the filtering capacity (3), determining at least in discharge the shorting of the converter-voltage raiser (1) with the direct passage of the current through said thyristor (41) as long as the voltage of the filtering capacity (3), which is substantially equal to the storage member voltage, is sufficient for the electric machines to provide the requested torque. The invention is particularly intended for a power-bypass hybrid vehicle, in particular for the continuous variation of the transmission ratio. |
