Abstract
This paper presents a comprehensive development of a dynamic wireless power transfer (WPT) system for the charge of the battery onboard an electric vehicle (EV). The development starts from the assessment of the electrical specifications of the dynamic WPT system, goes through the design of its power stages, and concludes with its validation. In the design step, the structure of the coupling set, layout of the coils, configuration of the conversion stages and topology of the compensation networks are illustrated, as well as electrical sizing of the power stage components. In the validation step, the setup of a dynamic WPT system is described, and the results of experimental tests carried out with the pickup moving along the track are given.
Highlights
The technology of contactless power transfer is the subject of intense research activity focused on various application areas [1,2,3]
The dynamic wireless power transfer (WPT) system developed in this paper is designed to charge the battery of an electric vehicle (EV) while horizontal road
It is worth to note that the power requirement in (3) and the ground clearance given in Table 1 place the considered dynamic WPT system in the WPT1/Z1 class defined in [19], which encompasses WPT
Summary
The technology of contactless power transfer is the subject of intense research activity focused on various application areas [1,2,3]. Specifications be Electrical sized to transfer onboard both the battery power Pb, max and the power drawn by the traction drive (TD) to move the vehicle Such a power is specified for the EV travelling at maximum speed on. The dynamic WPT system developed in this paper is designed to charge the battery of an EV while horizontal road In these conditions the force necessary to propel the EV is it is moving at its maximum speed. 2 of various research activities on sustainable mobility [18]
