Abstract
The present invention relates to a device () for powering a rotating electrical machine () of a motor vehicle, comprising: —an amplifier () capable of being electrically powered by the first electrical energy storage unit () and capable of electrically powering the second electrical energy storage unit (), characterised in that the amplifier () comprises an oscillating circuit (), the oscillating circuit () comprising a capacitance (C) of value C' and an inductive assembly comprising an inductance (L) of value L′ and a resistance (R) of value R′, —the oscillating circuit () having a specific angular frequency ω such that ω=I/√(L′×C′) and a natural frequency f such that f=ω(2π), and in that the value of the inductance (L) is variable in a predetermined manner, in particular so as to increase an electric current, supplied by the first electrical energy storage unit () to the oscillating circuit (), into an amplified current supplied by the oscillating circuit () to the second electrical energy storage unit ().
