This paper proposes a novel coupler structure for wireless power transfer, which takes advantage of both magnetic and electric fields. The coupler contains four metal structures, two each at the primary and secondary sides, which are capacitively coupled. Each structure consists of long strips of metal sheet to increase its self-inductance, which is then inductively coupled with the other three structures. The structures are vertically arranged, and the outer structures are larger than the inner ones to maintain the capacitive couplings. An external LCL compensation network is proposed to resonate with the coupler. The resonance provides conduction current flowing through each plate to establish magnetic fields, and displacement current flowing between different plates corresponding to electric fields. A 100W output power prototype is designed and implemented to operate at 1 MHz, and it achieves 73.6% efficiency from dc source to dc load at an air-gap distance of 18 mm. The contribution of this paper is to propose a concept to transfer power using magnetic and electric fields simultaneously. The potential application of this system is the charging of low power portable devices, such as laptops. After the coupler structure is optimized, it can be extended to higher power applications, such as vehicle charging.
