This paper deals with the numerical evaluation of the magnetic field produced by a wireless power transfer (WPT) system in an electrical vehicle (EV) made by carbon-fiber (CF) laminates that are modeled as homogeneous anisotropic layers. The numerically calculated magnetic field generated by a 7.7 kW WPT system operating at 85 kHz has been compared with the reference levels of the ICNIRP guidelines...
A study is presented on the magnetic field produced by a wireless power transfer (WPT) system installed in an electric vehicle (EV). The considered WPT charging system operates at the frequency of 85 kHz with an output power of 22 kW. The magnetic field levels are numerically calculated. In the simulations the presence of the conductive bodyshell of the vehicle is taken into account. The magnetic...
This study deals with the intrasystem electro-magnetic compatibility (EMC) issue produced by a Wireless Power Transfer (WPT) charging system applied to a pacemaker. A co-simulation circuit/field method is proposed to predict the induced voltage at the input port of the pacemaker.
The application of the Wireless Power Transfer (WPT) technology to a pacemaker for recharging its battery requires the pacemaker to be equipped with a secondary WPT coil. This coil acts as a receiving loop antenna for external electromagnetic fields. Thus, the induced current and voltage can be a source of EMI for the pacemaker circuitry. Aim of this study is to investigate how to reduce these induced...
