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.",

note = "Funding Information: I. INTRODUCTION Capacitive-based wireless Power Transfer (CPT) technology that has been extensively investigated over the last years finds its way into a broad spectrum of applications ranging from small, low-and medium-power appliances such as biomedical implants, LED drivers and mobile devices to high power electric vehicles, in-track-moving systems, and military platforms [1]-[4]. One of the most notable benefits of capacitive power transfer (CPT) over inductive power transfer (IPT) methods [5]-[8] is the absence of Eddy currents, making them less sensitive to the metal objects interferences. In addition, CPT technology offers low-cost, low-weight and simpler end-to-end construction [1], [8]-[12] as well as efficiency improvements. Systems exploiting the CPT technology typically employ high-frequency resonant conversion, in the range of several MHz, to achieve better power transfer characteristics and to further improve the overall power transfer efficiency [8]-[14]. ________________________________________ This work was supported by the Prof. A. Pazi Research Foundation A typical CPT system is shown in Fig. 1 and consists of a high-frequency inverter, high-frequency rectifier, and resonant matching networks.
