The invention provides a complementary coupling system applied to dynamic wireless power transmission, which comprises a segmented direct current bus for supplying direct current obtained after a power frequency power grid is rectified to an inversion-control module of a corresponding road section, and the inversion-control module inverts the direct current into high-frequency alternating current; the inverted high-frequency alternating current completes resonance with the primary multi-pole transmitting coil or the primary single-pole transmitting coil through the primary compensation network, transmits energy to the integrated receiving coil based on a near-field resonance coupling principle, and completes resonance with the integrated receiving coil through the secondary compensation network; the high-frequency alternating current is converted into stable direct current through the rectifying and filtering module and is output to a vehicle battery; wherein the multi-pole type transmitting coil and the single-pole type transmitting coil which are located on the primary side are alternately laid, and the integrated receiving coil is formed by connecting and overlapping a multi-pole type receiving coil and a single-pole type receiving coil in series. According to the invention, the advantages of the single-pole coil and the multi-pole coil are utilized, so that stable and efficient dynamic wireless power transmission can be achieved.
