N2 - This article provides a comprehensive analysis of the contactless resonant converters using a multicoil receiver set for high misalignment tolerance, with emphasis on the cooperative mechanism of multiple coils and a quantitative analysis of the operating characteristics. The collaborative operation of multiple receiving coils with various compensation circuits and connection types is discussed. A series–parallel compensated converter using a DD2Q receiver set with parallel connection for the multiple rectified outputs is used to illustrate the analysis procedure. Two methods are presented here, namely numerical calculation for the normal case and analytical derivation under three typical misalignments. With the help of switching functions, the general output voltage gain can be derived, which provides direct insight into the cooperation of multiple coils and a practical approach for reducing the output fluctuation. Simulation and experimental verifications are included to confirm the analytical results.
