Grazian, F. (author), Shi, W. (author), Soeiro, Thiago B. (author), Dong, J. (author), van Duijsen, P.J. (author), Bauer, P. (author)In high-power wireless battery charging that uses inductive power transfer, a considerable amount of power losses are located in the transmitter and receiver coils because they carry high resonant currents and typically have a loose coupling between them which increases eddy current losses. Therefore, the nominal operation needs to be chosen...conference paper 2020

Grazian, F. (author), Shi, W. (author), Soeiro, Thiago B. (author), Dong, J. (author), Bauer, P. (author)In inductive power transfer applications, it is possible to ensure high efficiency of the main coils by operating at the optimum load. Since the optimum load depends on the coupling between the main coils, the operation needs to be adapted to match this case at different alignment conditions. This paper proposes a method to keep the optimum load...conference paper 2020

Beloqui Larumbe, L. (author), Qin, Z. (author), Bauer, P. (author)A voltage imbalance at the AC terminals of a three-phase inverter creates a ripple in the power signal on the DC side. In order to minimize this ripple, several techniques can be applied, in which a double Synchronous Reference Frame (SRF) current control structure is very typical. In this approach, both the positive and negative sequence...conference paper 2020
