Test results for a combination of different numbers of Txs
and Rxs are shown in this section. Coil simulations in
Ansys/Maxwell and circuit simulations in LTSpice are
accomplished to validate the test results.
The testbench is shown in Fig. 6(D). The control board
carries the grid rectifier, a flyback converter and driving
circuit for the Tx as shown in Fig. 6(A). Fig. 6(B) shows the
Tx coil with an outer diameter of 17 cm. In Fig. 6(E) we can
see the two Tx topology. The angle between the two Txs is
fixed at 90°. In Fig. 6(C) the experimental receiver coil is
shown. It consists of an fixed and adjustable capacitance near
