Abstract :
Wireless power transfer (WPT) systems with multiple transmitters promise advantages over single transmitter systems, most predominantly a higher transfer efficiency. Using closed-form expressions obtained from convex optimization, the maximum achievable transfer efficiency and the required load resistance (impedance matching) values are investigated and compared against the single transmitter reference.
