Abstract
The present invention relates to a method for charging accumulation means via an external electrical network via at least a first (A) and a second (B) switching arm respectively comprising two switches (12), said method comprising a step for controlling the switches (12) of the switching arms (A, B) by transmission of pulse width modulation control signals, characterized in that the switches (12) of the second switching arm (B) are controlled by adapting the pulse width of the control signals so as to generate an alternating voltage (Vx) in phase opposition relative to the voltage at the terminals of a compensation inductance (7′) connected on the one hand to the second arm (B) and on the other hand to the neutral (N) of said network, so that the voltage (VN) between the neutral (N) of said network and ground is a direct voltage.The invention also relates to a charging device for implementing such a charging method.
