The thesis aims to realize an inductive/capacitive composite wireless power transfer system using the double-ring coaxial-coil type coupling structure for inductive wireless power transfer and with the electric field coupling capacitive wireless power transfer. The dual-frequency square wave signal containing low frequency and high frequency, generated by the full-bridge converter, is used as the excitation source. Through the hybrid resonance compensation network, the double-ring coaxial-coil enables both series resonance compensation for inductive transfer at low frequency and equivalent LC series resonance compensation for capacitive transfer at high frequency. When the distance between the transmitting coil and the receiving coil is 7 cm, and the excitation source is a dual-frequency square wave signal containing 20 kHz and 300 kHz, the inductive/capacitive composite wireless power transfer system with dual operation frequency achieves an output power of 188.49 W and a transmission efficiency of 87.26%.
