Microwave power transfer (MPT) is one of the most promising systems in the long distance wireless power transfer system. In MPT system, conventional diode rectifying circuit produces harmonic energy which has great impact on the overall efficiency as well as the power reflection. In order to gain adaptive impedance matching and high efficiency, this paper applies power electronic devices and topology to construct a two-stage 100MHz converter. 100MHz belongs to the radio frequency (RF) and belongs to the conception of microwave frequency. The two-stage adaptive impedance matching circuit and its control method are evaluated by simulations. The design of microstrip antenna is also presented in this paper, experimental results are shown to verify the effectiveness of the proposed RF-DC converter and the efficiency is up to nearly 65% as well.
