    • A method for managing a power supply system with a variable voltage comprising the following steps: according to an instantaneous rotational speed of a rotating electrical machine, a power supply system output voltage with a variable voltage is set to an optimum output voltage between first and second service voltages in such a way as to maximize the electric power delivered by the electrical machine to an energy storage system; when the instantaneous rotational speed is slower than the nominal rotational speed, the output voltage is set to a first value which is substantially equal to the first service voltage in such a way as to maximize the yield of the transfer of energy from the electrical machine to a load; and when the instantaneous rotational speed is faster than the nominal rotational speed, the output voltage (U) is set to a second value substantially equal to the second service voltage in such a way as to maximize the yield of the transfer of energy from the electrical machine towards the load.
