Abstract: The invention relates to a method for charging a vehicle battery by induction from a charging device including a charge transmitter including a primary coil L1 and an inverter capable of supplying the primary coil L1 with an AC supply voltage E. Said device also includes a charge receiver including a secondary coil L2 arranged in a vehicle. Said method consists of adjusting a frequency f of the power supply voltage (E) to the resonance frequency fo, when a motor vehicle is located in a parking space.

Abstract: The energy conversion system comprises a primary and a secondary modules. The primary module includes input terminals, a primary winding, and a primary capacitor connected to the primary winding and the input terminals. The secondary module includes output terminals, a secondary winding and a secondary capacitor connected to the secondary winding and the output terminals. A current is induced in the secondary winding when the primary and secondary windings are magnetically coupled, the current received between the input terminals flowing through the primary winding. The secondary module comprises a secondary switch electrically connected to the secondary capacitor and the secondary winding, and means for controlling the secondary switch, between a first configuration wherein the current induced in the secondary winding flows up to the output terminals, and a second configuration wherein said induced current flows in a closed loop through the secondary winding and the secondary capacitor.

Abstract: This electrical energy conversion system, for powering a load using a voltage source, comprises a first capacitor, a second capacitor, two load connection terminals and an electrical transformer comprising a primary winding and a secondary winding.
