摘要：
Wireless power transfer (WPT) techniques can provide safe and more convenient methods for charging electric scooter than the conventional method of wired charging. However, there is a specific zone of the charging platform for high-efficiency power charging. If the RX is not within the zone or misaligns from this zone, the transfer efficiency will deteriorate. Therefore, we propose a repeater array architecture to improve the coupling between TX and RX and increase the transfer efficiency. The simulation result show that the efficiency can reach 74.8% with a larger distance between TX and RX of 20 cm.
