N2 - With the construction of the DWPT system towards the kilometer level, the number and length of power rails increase, and the inductance and resonance voltage also increase significantly. This puts forward higher requirements for high-level insulation materials and insulation distance, poses significant safety risks, and restricts system integration. This article proposes a distributed compensated bipolar power supply rail structure and verifies its low inter-turn voltage characteristics through theoretical analysis and simulation. The electric field simulation results show that the maximum inductance voltage stress in the 4-pole power rail decreases from 8.9 kV to 0.53 kV, reducing by 94% compared to the unimproved rail. Maximum inter-turn voltage decreased from 7.29 kV to 0.84 kV, reducing by 88% compared to the unimproved rail. At the same time, the volume of the power rail has also decreased by 8.3%.
