Learn the principles of operation and see example implementations of a wireless charging system based on the Qi standard
Watch this 1-hour recording to gain a solid understanding of wireless charging concepts and the key aspects of the WPC (Wireless Power Consortium) Qi standard. The video wireless charging solutions from ST for both the Transmitter (STWBC series) and Receiver (STWLC3x series), illustrating how they can be used to implement complete wireless charging systems in the 1 W - 15 W power range that include support for proprietary fast-charging methods for mobile phones. Also discussed, is reduced-size coils systems for small form-factor applications such as wearables.
You will learn:
- How Qi wireless charging works, and the key differences between this and other standards
- The most important operating aspects of a Qi system
- About the reference designs and evaluation boards available from ST
- The key features and advantages of ST's wireless charging solutions
