  • Electric circuit for charging at least one electrical energy storage unit by means of an electrical network
    Patent number: 9744868
    Abstract: An electric circuit (5) for charging at least one electrical energy storage unit (4) by means of an electrical network, the circuit (5) comprising: an inductive cell (6) configured to interact with an inductive cell of the electrical network to exchange energy by electromagnetic induction, a rectifier (13) disposed downstream from the inductive cell (6) and whereof the positive output terminal (17) and the negative output terminal (20) are each connected to a conductor (18, 21) of a DC bus (19), a capacitor (22) mounted between the two conductors (18, 21) of the DC bus (19), a power stage (25) whereof the positive input terminal (26) and the negative input terminal (27) are respectively connected to one of the conductors (18, 21) of the DC bus (19), and which is configured to adapt the value of the DC voltage between the positive input terminal (26) thereof and the negative input terminal (27) thereof to the electrical energy storage unit (4), the power stage comprising, at most, two voltage converters, and t
