Abstract

The present invention is a wireless power transfer system (10) for charging batteries in a wireless manner, wherein said wireless power transfer system (10) comprises an inverter (150) connected to a first end where DC input voltage is provided and arranged to transform said input voltage into sinusoidal waveform at a f1 frequency; and a transmitter circuit (160) associated with the inverter (150) which receives the voltage in sinusoidal waveform received from said inverter (150); said transmitter circuit (160) comprises a first winding (161) for providing transferring of the voltage, received from the inverter (150), in a wireless manner; said wireless power transfer system (10) further comprises a receiver circuit (210) having a second winding (211) associated with the battery (300) to be charged; a control unit arranged to monitor the phase difference angle between the first voltage and the inverter (150); and the control unit is arranged to gradually increase the f1 frequency until the phase difference exceeds 0 and to provide continuation of the power transfer process with the obtained f1 frequency when the phase difference exceeds 0 or is equal to 0.
