Abstract
The present disclosure relates to the field of EV-DWPT (electric vehicle dynamic wireless power transfer), and specifically discloses a double solenoid EV-DWPT system and a parameter optimization method thereof. The system is provided with a magnetic coupling mechanism, comprising a transmitting structure and a receiving structure. The transmitting structure includes a plurality of double solenoid transmitting rails arranged equidistantly along a road direction. Each double solenoid transmitting rail includes a square tubular magnetic core perpendicular to the road surface, and transmitting solenoids wound spirally using one and the same Litz wire wound in opposite directions. The present disclosure proposes a magnetic coupling mechanism with a double solenoid structure, provides a specific parameter optimization design method, completes the analysis of the system power transmission topology and the electrical parameter design, greatly reduces power fluctuations of the system rail switching domain, and improves the system's anti-offset capability.
