Disclosed are a method for controlling wireless power transmission to an electric vehicle using a bridgeless rectifier and a device thereof. The method for controlling wireless power transmission to an electric vehicle using a bridgeless rectifier comprises the steps of: detecting a phase difference between the input voltage of a transmission side resonance circuit and the output voltage of a reception side resonance circuit; predicting a resonance frequency change direction in accordance with a preset design condition when the phase difference is detected; and controlling an operation time of switches included in the bridgeless rectifier in a direction of compensating for the predicted change direction.

    브리지리스 정류기(bridgeless rectifier)를 이용하여 전기차로 무선 전력 전송을 제어하는 방법 및 장치가 개시된다. 브리지리스 정류기(bridgeless rectifier)를 이용하여 전기차로 무선 전력 전송을 제어하는 방법은, 송신측 공진 회로의 입력 전압과 수신측 공진 회로의 출력 전압 사이의 위상차를 감지하는 단계, 상기 위상차가 감지되면 미리 설정된 설계 조건에 따른 공진 주파수 변화 방향을 예측하는 단계 및 예측된 변화 방향을 보상하는 방향으로 상기 브리지리스 정류기에 포함된 스위치들의 동작 시점을 제어하는 단계를 포함한다.
