S-P-S compensation topological structure and system based on three coils

The invention discloses an S-P-S compensation topological structure based on three coils, which comprises a primary side compensation network, a primary side transmitting coil, a third relay compensation network, a third relay coil, a secondary side receiving coil and a secondary side compensation network, and is characterized in that the primary side transmitting coil and the third relay coil are mutually decoupled; and the secondary receiving coil is coupled with the primary transmitting coil and the third relay coil. The invention further discloses a wireless electric energy transmission system adopting the S-P-S compensation topological structure, the primary side current can be minimized in a wide offset and wide load range, and zero voltage switching is ensured to be realized in all working condition ranges, so that the system efficiency under the conditions of light load and low coupling is improved. 本发明公开了一种基于三线圈的S-P-S补偿拓扑结构，包括原边补偿网络、原边发射线圈、第三中继补偿网络、第三中继线圈、副边接收线圈、副边补偿网络，原边发射线圈与第三中继线圈彼此之间相互解耦，副边接收线圈与原边
