Abstract
In this contribution, the authors investigate a modular structure of a wireless power transfer (WPT) system specifically dedicated to a quasistatic or dynamic operation mode in an urban environment. The proposed architecture has been simulated by using commercial software. Characteristics of the interoperability are analyzed when the modular transmitting and receiving coils are in proximity, and the architecture has proven to be characterized by excellent performances in terms of small interaction between each single module. Finally, an improved coil design has been introduced which is characterized by good uniformity of the coupling coefficient when the receiver travels between two adjacent transmitting sections.
