Design of Dual-Frequency Rectifier in Wireless Power Transfer Systems <Abstract> In this paper, we propose a dual-frequency rectifier with a compensated zero-impedance angle in wireless power transfer (WPT) systems. By designing capacitive and inductive elements across multi-frequencies, the rectifier uses a single T-type topology to form a dual-frequency LCC compensation, ensuring the zero-impedance angle. Experimental results confirm that the rectifier can transmit power at dual frequencies. The WPT systems with the proposed rectifier achieve high efficiencies of 80.8% and 86.6% at 3.39 MHz and 6.78 MHz, respectively. This verifies the effectiveness of the proposed rectifier. |
