Abstract
【解決手段】無線電力伝送方式で電気エネルギーを供給する無接点電力送信装置(100)の充電デッキに置かれる物体を感知して、無接点電力受信装置(200)が置かれた場合だけ、電力送信及びデータ通信ができるようにすることで、受信側の状態を正確に認識して、効率的に電力を制御することができる。また、無接点電力受信装置(200)に供給される電力を測定して、お互いに異なる二つのコアで送出される無線電力信号の出力電力を制御することで、安定的な充電が成り立つことができる。特に、無接点電力受信装置(200)が無接点電力送信装置(100)上で移動をする場合でも、安定的に電力を供給できるようにした。
