Assessment of electromagnetic field exposure for dynamic and stationary wireless power transfer system in various human body positions

초록

For wireless charging systems operating at high powers of up to tens of kW, high-intensity electromagnetic fields can have a significant impact on surrounding electronic devices and the human body. In this study, Electromagnetic Field (EMF) simulations were performed for stationary charging modules targeting electric vehicles (EVs) and dynamic charging modules targeting EV buses, and the derived magnetic field data was used to perform induction analysis inside a human body model. Five scenarios assuming the worst exposure situation are provided, and the intensity of the magnetic field and the induction inside the human body were compared and evaluated with international guidelines (ICNIRP). The results of this study can be used to secure the safety of wireless charging modules and design criteria for shielding structures.
