Impact of onboard DC-DC Converter for Dynamic Wireless Charging of Electric Vehicles

Dynamic wireless charging (DWC) system is a promising contender for the implementation of charging infrastructure and uphold the consumer prejudices. In this article the main emphasis is on the impact of onboard dc-dc converter for the DWC application. The purpose of carrying out this work is to understand the footraces of load independent operation and zero phase angle operation. These characteristics are very much essential for the better, efficient and safe design of the DWC system to charge the battery from the supply grid. Further, on simulation models for different compensation systems with and without onboard dc-dc converter analyzed. Finally, it is found that-series series (SS) compensation is effective for the DWC with onboard dc-dc converter as compared to the DWC system without onboard dc-dc converter in terms of its characteristics pertinent to the load independent operation and efficiency.
