UNIT COMPRISING AN ELECTRIC POWER SOURCE INCLUDING AT LEAST TWO ELEMENTS OF DIFFERENT TECHNOLOGIES AND AN INVERTER FOR CONTROLLING AN ALTERNATING-CURRENT ELECTRIC MOTOR

摘要

The invention relates to a unit comprising an electric power source including at least two elements of different technologies and an inverter for controlling an alternating-current electric motor, said driving inverter comprising: an alternating-current generator (3) that delivers a current to a terminal (4) intended to be connected to the phases of an electric motor (6); a supply line (20); an alternating-current collector (41, 42) on certain phases supplying the electric motor; a current collector (21) on the supply line; an input (52) receiving information including at least one "source current limit" value and a requested torque setpoint; and a controller (5) controlling the phase currents of the electric motor as a function of the torque setpoint, while maintaining the supply line current at an acceptable value depending on the source current limit. Consequently, a maximum current can be imposed at any time on the current source without risk of impairing same.
