A simplified block diagram of a descriptive CPT system is shown in Fig. 1. It consists of a high-frequency inverter in the transmitter’s unit and a high-frequency rectifier on the receiver’s side. In addition, similar to IPT systems, reactive matching networks in both the transmitting and the receiving units are used between the transmitter and the receiver [11]-[13]. The core element of CPT systems is the Capacitive-Coupler (CC), through which the energy is transferred by an electric field from ________________________________________ This work was supported by the Prof. A. Pazi Research Foundation the transmitter to the receiver. The CC interface is typically constructed using two pairs of conductive coupling plates (Fig. 1), such as copper foils or aluminum sheets [6], [10], [14]. The resulting coupling capacitances primarily depend on the area of the plates, distance, and the dielectric material between the plates [6], [10], [15]-[17], which in turn are chosen according to the application requirements.

N2 - This study examines and compares several electrical models of capacitive-couplers (CC), which are a fundamental unit in capacitive power transfer (CPT) systems, responsible for the power transfer between the transmitter and the receiver. The applicability and implementation of the models under study in static and dynamic simulation analyses are presented and discussed in detail. The study further explores a series (Thevenin) model of CC, which consists of a dependent voltage source in series with a capacitor, on both receiver and transmitter sides, and shows its advantages over other models in simplifying system analysis and dynamic simulations. The model has been verified by FEA simulations and by experiments. The experimental results are in a good agreement with the theoretical analysis and the simulations.
