摘要：

The high-power wireless power transfer (WPT) system in railways does not require physical contact to transfer electrical power, is electrically safe, and reduces maintenance costs from wear and tear. However, a high-power system generates a strong magnetic field that can result in problems of electromagnetic field (EMF) exposure and electromagnetic interference (EMI). In this study, EMF and EMI were measured at various positions under in-motion environment conditions for a 1-MW WPT light rail transit system. The measured maximum EMF was 2.41 mu T, which is lower than the international guideline of 6.25 mu T for the various locations with a potential presence of passengers. The measured EMI also satisfied international standards in the frequency range of 150 kHz-1 GHz.
