“…This structure is a four-plate parallel structure with two extra shielding plates to provide better protection against electric fields, as seen in Figure 14 d. The additional plates do not take part in the power transfer and are only coupled via parasitic capacitance. Studies have shown that this approach improves safety and efficiency [ 23 , 24 , 25 , 26 ].…”

Wireless power transfer provides a most convenient solution to charge devices remotely and without contacts. R&D has advanced the capabilities, variety, and maturity of solutions greatly in recent years. This survey provides a comprehensive overview of the state of the art on different technological concepts, including electromagnetic coupled and uncoupled systems and acoustic technologies. Solutions to transfer mW to MW of power, over distances ranging from millimeters to kilometers, and exploiting wave concepts from kHz to THz, are covered. It is an attractive charging option for many existing applications and moreover opens new opportunities. Various technologies are proposed to provide wireless power to these devices. The main challenges reside in the efficiency and range of the transfer. We highlight innovation in beamforming and UV-assisted approaches. Of particular interest for designers is the discussion of implementation and operational aspects, standards, and safety relating to regulations. A high-level catalog of potential applications maps these to adequate technological options for wireless power transfer.

“…Abramov et al present a model to realize cross-coupling relationships between input and output ports of the CPT system [103]. The six-plate coupling structure includes active four plates inside and larger passive two plates behind to reduce electric field emissions [104][105][106][107][108][109]. The electric field repeater is proposed to increase the transfer distance [110].…”

Capacitive power transfer (CPT) technology is becoming increasingly popular in various application areas. Due to its limitations, such as low frequency, low coupling capacitance, and the high voltage stress on metal plates, the studies on high power CPT applications fell behind previously. Therefore, the wideband gap (WBG) semiconductor devices and the compensation topologies are further adopted to tackle these limitations. The main purpose of the paper is to review CPT applications in terms of performance parameters, advantages, disadvantages and also challenges. Initially, the basic principles of CPT technology are examined, which cover compensation topologies, coupler structures, transfer distance, power electronic components, and system control methods. Then, CPT applications are evaluated for performance parameters (i.e., power level, operation frequency, system efficiency, transfer distance) along with compensation types, inverter types, and coupler types. The applications are categorized into six main groups according to industrial topics as safety, consumer electronics, transport, electric machines, biomedical, and miscellaneous. Herein, power level changes from µW to kW ranges, the operation frequency varies from 100s of kHz to 10s of MHz ranges as well. The maximum system efficiency is recorded as 97.1 %. The transfer distance varies from µm range to 100s of mm ranges. The full-bridge inverter topology and four-plate coupler structure are noticeable in CPT applications. Finally, advantages, disadvantages, and challenges of CPT applications are evaluated in detail. This review is expected to serve as a reference for researchers who study on CPT systems and their applications.INDEX TERMS Capacitive power transfer, capacitive coupling, wireless power transfer.MEHMET ZAHID EREL was born in Sakarya, Turkey.

The purpose of this study was to analyze the impact of local community power on green tourism (after this, abbreviated as GT). The analytical features were as follows; First, we derived the concept of local community power from "agricultural village activity," "local activity", and "regional support," to describe the degree of cooperation and collaboration among people who use local resources related to agriculture. Second, a theoretical model for the impact of local community power on GT was developed and analyzed. Third, a covariance structure analysis was conducted on the relationships between local community power and GT using data from the 2015 agricultural census. Results of the analysis revealed that local community power has a positive impact on green tourism.
