Problems solved by technology

[0004] However, because the power supply system is a single-phase high-frequency power supply, the cable is a single cable, and usually the area surrounded by the cable is large, resulting in a large magnetic flux leakage, which loses most of the electromagnetic energy, and the power that can be transmitted to the rail train is relatively small. Small, making the energy efficiency lower
