Abstract

Capacitive-based wireless Power Transfer (CPT) has been proven as a reliable and efficient technology for many applications ranging from small appliances such as biomedical implants to high power electric vehicles. The energy in CPT systems is being transferred by means of an electric field, which implies that the system must comply with safety regulations regarding human exposure to EMF emission. This study introduces a methodology of applying a multistep simulation for estimating electric fields generated by CPT systems. No prior knowledge of the voltages on the capacitive coupler is required. Due to the sequential nature of the proposed workflow, it can be executed either manually or as a part of an automated procedure. The proposed approach is demonstrated in this study on a wireless charger for a toddler's rechargeable car.
