• This paper proposes a selective driving algorithm for a high-efficiency operation of an inductive power transfer (IPT) system in which the double-D quadrature pad (DDQP) is applied. Initially, the IPT pads are manufactured, and the coupling coefficients are measured according to the pad misalignment. Subsequently, the driving algorithm and compensation network of the IPT converter are designed according to the measurement results. After that, the loss analysis is conducted through the simulation to evaluate the designed IPT converter, and the efficiency before and after applying the proposed driving algorithm to the IPT converter is compared to demonstrate the feasibility of the algorithm. Finally, the experimental waveforms are suggested to validate the design of the DDQP - CP IPT system.
