摘要
Wireless power transfer (WPT) is promising for electric vehicle (EV) charging as it is able to transfer power in a non-contact manner. This paper presents a comparison between the series and parallel hybrid compensation topologies, and with the normal series and parallel compensation networks as reference. Those two hybrid topologies are dual-circuits where the negative feedback in the main power transfer channel is built using the complementarity characteristics between the normal series and parallel compensation network. As the WPT pad misaligned, those dual-circuits do not require sensors and feedback controllers but are able to against the variation of the system-critical parameters. Meanwhile, those dual-circuits have different charging profiles that may be suitable for different EV wireless charging scenarios. Therefore, a side-by-side comparison in the 3.3 kW system charging profiles, with a 400 mm air gap with 160 mm lateral and longitudinal pad misalignments, are taken into consideration. The system efficiency, ZVS operating region are all presented in order to clarify the key advantages, as well as the limitations of the hybrid compensation topologies with considering the practical end-user experience.
