Wireless charging – power transfer
Please choose a subcategory
Cut the cables – and charge your devices without wires
It’s a familiar story: You want to make a call but your smartphone battery has just died. Up until now, you would have had to find the charging cable, connect it to your phone and then plug it into an outlet. Which is all fine. But it can still be a hassle. Especially if you can’t find your cable or the one you have doesn’t fit the jack on your phone. Wireless charging changes all that. It uses electromagnetic fields to transfer power from a transmitter to a receiver application. In short, it charges your battery without a physical connection.

Wearables
Wearables are electronic devices that are comfortably worn on the body. Infineon’s 2 W inductive and 2.5 W resonant solutions enable wearables to be easily charged without any physical connections to a power source.
For application requirements, ranging from just a few watts up to kilowatts
There are many reasons why you should include wireless charging into your application. There are, of course, the obvious ones – you no longer have to plug in your device or worry about plug compatibility issues. But wireless charging is also safer since there is no contact with exposed electrical connectors. What’s more, wireless charging is more reliable in harsh environments such as industrial and outdoor locations because it enables completely sealed system designs. And with wireless charging technology becoming more widespread in public spaces and in private and public transportation, you can quickly and easily charge your devices on the go. You can also charge multiple devices without having to untangle charging cables.
Wireless charging is a complex subject that requires in-depth system knowledge and expertise. Designers have to understand antennas and how they interact with surrounding structures. To successfully transfer power wirelessly, the power delivery has to be precisely controlled. By working closely with our experienced partners, we can help customers master all design challenges, including:
- Compatibility issues
- Safety issues
- Smart heat management
- Increasing efficiency and reducing charging times
- Preventing device and battery damage
The two wireless charging standards currently adopted in the market are inductive and resonant charging:
