Abstract

In this paper, medium-power wireless power transmission is implemented using the commercial power frequency (60 Hz). Since general magnetic induction wireless power transmission devices use more than several tens of kHz, the commercial power frequency (60 Hz) cannot be used as is. Therefore an AC/DC converter is used to convert the 60 Hz power frequency into DC, and a high-frequency power amplifier is used to convert DC into several tens of kHz. In magnetic induction wireless power transmission, the AC/DC converter and high-frequency power amplifier are removed, and a extremely low frequency wireless power transmission(ELF-WPT) system using commercial frequency consisting of only transmitting resonance tank, transmitting coil, receiving resonance tank, and receiving coil is implemented, and verified through wireless power transmission experiments.

본 논문에서는 상용전원 주파수(60 Hz)를 사용하여 중전력 무선전력전송을 구현한 것이다. 일반적인 자기유도 무선전력전송 장치는 수십 kHz 이상 사용하기 때문에 상용전원 주파수(60 Hz)를 그대로 사용할 수 없고, 교류/직류 변환기를 사용하여 60 Hz 전원주파수를 DC로 만들고, 고주파 파워앰프를 사용하여 DC를 수십 KHz로 만들어서 사용한다. 자기유도 무선전력전송에서 교류/직류 변환기와 고주파 파워앰프를 제거하고, 송전 공진탱크, 송전코일, 수전 공진탱크, 수전코일 만으로 구성한 상용전원 주파수를 사용하는 극저주파 무선전력전송 시스템을 구현하고, 무선전력전송 실험으로 검증하였다.
