Abstract

A method is disclosed for controlling a transmitter (20, 30) for wirelessly charging a power storage unit of an electric vehicle comprising a receiver (22, 32 with a secondary resonant circuit (L2, C2). The transmitter comprises a first resonant circuit (L1, C1), an inverter (23) with switches (SW1, SW2, SW3, SW4) and a driver (24) to control the inverter. The method comprises receiving by the driver (24), from a controller (25, 35), commands to set the switches of the inverter (23) in a first position when the instantaneous inductor current (i<1>, i<2>) in the primary/secondary inductor (L1, L2) passes through zero in one direction, and in a second position when the instantaneous inductor voltage (v<L1>, v<L2>) across the primary/secondary inductor (L1, L2) reaches a voltage reference, or when a quantity representative of a total instantaneous power stored in the primary/inductor (L1, L2) reaches a power reference.
