This paper proposed a model of Contactless Power Transfer System (CPTS), which adopted a transformer with big air-gap and long primary wires. The system has the characters of long leakage inductance, small magnetizing inductance and low coupling coefficient. The proposed model can improve system efficiency by adopting resonance of compensation capacitance and leakage inductance in transferring energy to the load. The Maxwell/IsSpice simulation is applied to verify the feasibility. A contactless power transfer system for linear track is confirmed. The experimental evidence reported 0.21ω primary coil impedance and 7A primary current. The transferring efficiency of CPTS can reach up to 76%.
