Abstract:
1. A system for electrical energy exchange between at least one motor-generator element and at least one storage element determining a DC storage voltage between two branches of a bus circuit to which are wired in parallel a voltage-booster DC/DC converter, a filtering capacitor for delivery by the converter of a requested voltage between a positive bus and a negative bus, and a DC/AC converter wired to at least one motor-generator element, the system comprising: at least one thyristor wired in a bypass fashion to the positive bus, between the storage element and the output of the voltage-booster converter, so as to short-circuit the voltage booster converter; and means for priming the thyristor as a function of voltage requested from the filtering capacitor, determining, at least in discharge mode, the short-circuiting of the voltage-booster converter with direct passage of the current through the thyristor, as long as the voltage of the filtering capacitor substantially equal to the voltage of the storage element, is sufficient.
