Abstract

This paper aims to suppress the resonant frequency drifting of the transmitter of the one-to-multiple wireless power transfer (OWPT) system, which is caused by the reflected impedances of the unselected receivers. To overcome the frequency drifting of the transmitter and realize the full resonant of the whole circuit, it is necessary to dynamically change the compensation capacitor with tuning the circuit of the transmitter. However, with more receivers, the range of capacitance of the compensation capacitor increases. So, it leads to the increasing of the difficulty in making the capacitor array. In this paper, to cancel the unexpected frequency drifting and narrow the range of the compensation capacitor, as well as to decrease the size of the capacitor array of the transmitter, the using of hybrid compensation topology in receivers is proposed. First, based on the existing OWPT system, the hybrid compensation topology is proposed and analyzed in details. Then, the guidelines for parameters design of the transmitter is presented and analyzed in details. Finally, the simulation results are given to validate the proposed method. © 2019 IEEE.
