The coupling coefficient as well as the operating frequency increases or decreases the load power in a wireless power transfer system. The parameter space of coupling coefficient and operating frequency is divided into over-, critically-, and under-coupled regions. The load power at over- and under- coupled regions drops from the critically-coupled region where the power is ideally maximized. This situation for series–series topology has been clarified in the conventional studies. In this paper, the critically-coupled region or critical coupling coefficient for series-parallel and parallel-series topologies is revealed in a mathematically form. The results of this paper suggest a selection of topology to improve load power over longer distance in wireless power transfer.

A cooperative control of wireless power transfer system using two transmitters Reviewed

Aims Electronics and Electrical Engineering 10 ( 1 ) 129 - 149 2026.1

A wireless power transfer system with a single transmitter fed by a voltage source and a single receiver with a load is widely studied to increase load power. A system with two transmitters is also studied, especially by controlling currents through transmitter coils to maximize load power, which means current sources to drive transmitter coils are assumed instead of the voltage source. This paper presents a method for adjusting voltage amplitude and phase of each voltage source embedded in two transmitters to maximize load power. The maximized load power is also presented in an explicit form based on circuit constants of the system. As a result, advantages of the two transmitters system over the single transmitter system are revealed from the perspective of efficient power delivery.
