Power Transfer Efficiency Analysis of Intermediate-Resonator for Wireless Power Transfer
IEEE Transactions on Power Electronics, 2018We investigate the effect of intermediate resonators (i.e., intermediate receiver (i-Rx) or relay) on the power transfer efficiency (PTE) for nonradiative wireless power transfer (WPT) with transmitter (Tx), intermediate-resonators, and end receiver (e-Rx).
