New Insight of Maximum Transferred Power by Matching Capacitance of a Wireless Power Transfer System [PDF]

Energies, 2017
Most research on wireless power transfer (WPT) has been focused on how to achieve a high-efficiency power transfer. Our study found that under the impedance matching for achieving maximum WPT efficiency, the power transferred to the load cannot reach the maximum when a WPT system is supplied by an AC voltage source with constant amplitude. However, the
