Abstract
A method for controlling wireless power transfer to an EV using a bridgeless rectifier may include detecting a phase difference between an input voltage of a transmission-side resonance circuit and an output voltage of a reception-side resonance circuit; after detecting the phase difference, predicting a resonance frequency change direction according to a preconfigured design condition; and controlling switching time points of switches included in the bridgeless rectifier in a direction compensating for the predicted change direction.
