Abstract
A dynamic wireless power transfer (DWPT) extends the driving range of an Electric Vehicle (EV). The dependency of the bulk volume energy storage device can be reduced by electrified highways. The effective concern on the design of charging pads will improve the power transferring profile and the constant charging. The life cycle of the batteries will be increased by DWPT technology. There are several issues related to the coil design in the DWPT system including sensitive misalignment tolerance, volume to weight ratio of the couplers, and electromagnetic exposure limits. The SAE J2954 guides the designer by their developed standards on the DWPT charging system. The power transfer capability of the charging pads maintained maximum level during misalignment conditions by compensation network. The charging couplers positioned on the roadside has driven by an expandable multiple leg converter. The five-leg converter is proposed in this paper to energize the four charging couplers and the single receiver is used to charge the battery.
