Wireless EV charging station
Overview
Our integrated circuits and reference designs help you create smarter and safer wireless electric vehicle (EV) charging stations. Whether a WPT1, WPT2 or WPT3 charging subsystem, we can help enable your design to efficiently transmit and receive power from a single, three-phase AC outlet.
Design requirements
Modern wireless EV charging stations often require:
- High-efficiency PFC stage followed by isolated or non-isolated inverter power stage.
- Foreign object detection of any object, especially metallic material.
- Live object protection with false trigger avoidance to create a virtual safety circle.
- Accurate, precise superposition of transmit and receive power coil.
