Nowadays, inductive power transfer is of great interest to the system working with electric power by virtue of its safety, reliability, and convenient characteristics. In fact, efficiency and compactness are the two parameters which play an important role in recharging electric vehicles. Double‐D quadrature pad (DDQP) is a suitable magnetic structure that due to the use of an additional coil, can enhance the X‐axis tolerance. Although there are several compensation methods to boost the efficiency, series and inductor–capacitor–capacitor (LCC) compensation types seem to be more practical and optimal. In this study, the LCC and series compensations are used together in the DDQP as the receiver side and calculated the value of the primary capacitor for enhancing the efficiency. Moreover, it is shown that, in the misaligned position which compensation has a better performance when utilising in the quadrature coil. Also, it is demonstrated that for making a system more compact, the quadrature and compensated coils integrated with the main coil in the secondary side do not have any significant effect on each other, neither on the other coils. Finally, the double‐D pad transmitter and DDQP receiver with the integrated LCC compensation method is prototyped to verify the results.
