| ABSTRACT |
|
In magnetic resonance coupled wireless power transfer (WPT) systems, parameters were investigated in the
WPT system to ensure maximum power transfer under the conditions of changing the distance between the receive coil and
the transmit coil. When the distance between the transceiver coils is changed, the inductances of the system and the coupling
coefficient for maximum power transfer were calculated with Maxwell-3D, which performed a solution based on the finite
element method (FEM). In addition, the effect of the distance variation between the transmitter and receiver coils, the
coupling coefficient (k) values, on the input inductance and power transmission was investigated. In the model developed in
the ANSYS-Maxwell environment, it has been observed that the variation of the input inductance depending on the distance
and therefore the common inductance between the transmitter and receiver coils can be analyzed. In addition, the effect of the
coupling factor (k) on the WPT system has also been demonstrated. It has been shown that maximum power transfer can be
sustained in WPT systems where the distance between the receive coil and the transmit coil varies within certain limits.
Finally, the efficiency of the transformer for a close distance between the coils was also tested experimentally. |
