무선전력전송(WPT: Wireless Power Transmission) 기술은 최근 개인 휴대기기에 대한 무선충전과 전기자동차 무선충전을 중심으로 비약적인 발전을 이루고 있는 기술이다. 또한 보다 높은 자유도와 안전성을 부여하기 위해 보다 먼 전송거리를 확보하고 다양한 이종기기에 동시에 전력을 공급할 수 있는 기술을 개발하기 위해 노력하고 있다. 이와 더불어 해당기술에 대한 독립적 지위를 확보하기 위한 다양한 표준화 활동이 동시에 진행되고 있다. 본고에서는 이러한 무선전력전송의 기술발전 동향과 표준화 동향을 소개하고, 향후 무선전력전송 기술의 발전방향에 대해 논하고자 한다.
