Abstract (en)

[origin: WO2020260032A1] Electrical circuit (1) for charging a DC voltage source from an AC voltage network, the circuit comprising: - an input (3) suitable for receiving an AC voltage from the voltage network, - a first output (4) suitable for being connected to the DC voltage source, - an insulation stage formed using several condensers (30, 31, 32, 33), arranged so as to electrically insulate the input (3) from the first output (4) of the circuit, and - a frequency increase stage (6) arranged between the input of the circuit and the insulation stage such that the condensers of the insulation stage are in a portion of the circuit traversed by an AC current at a frequency greater than that of the AC network.
