Cut the cables and charge without wires

Imagine your smartphone’s battery is dead. Until now, you first must find the charging cable, then connect it to your phone and finally plug it into an outlet. The process works, but it can be a nuisance. Especially if your cable is playing hide and seek or if the jack doesn’t fit the cable. Wireless charging removes the hassle of re-fueling your devices. By using electromagnetic fields to transfer power from a transmitter to a receiver application, it charges your battery without a physical connection. All thanks to a wireless charging power supply.

Now compatible devices from a wide range of receiver applications can fuel up cable-free. Currently, inductive or resonant solutions can be used for the following applications:

Smartphones and wearables

Notebooks and tablets

Power tools and service robots, such as vacuum cleaners

Multicopters and electric toys

Medical devices

In-car charging

There are many reasons why you should choose wireless charging for your application. In addition to the obvious ones, like no need to plug in a device and no plug compatibility issues, it’s also safer since there is no contact with exposed electrical connectors. Further, it’s reliable in harsher environments, such as drilling and mining. It also allows for seamless on-the-go charging whether in the car or in public places. Finally, it eliminates tangled charging cables while allowing you to charge multiple devices in parallel.

Inductive wireless charging – in-car charging

Driver comfort, convenience and safety are advancing the growing presence of wireless in-car charging in the latest generation of cars. In fact, it’s predicted that most cars will have the feature in the very near future. The technology allows drivers and passengers to simply place compatible cell phones and tablets in a designated area – typically on a tray in the center console or in the glove box – where the devices can charge without a wired connection.

What counts in today’s wireless charging designs

Power efficiency is of utmost importance in any new power design and wireless in-car charging is no exception. Furthermore, a wireless in-car charging system is integrated alongside many other vehicle applications. This means you are challenged to design a wireless charging power supply that does not interfere with other systems. A partner with expertise in automotive and wireless charging applications can help you do so with ease – and ensure a fast time to market. Last but not least, in an era of smart everything, you want to ensure your project offers the right security and communication features.

Mastering today’s wireless charging designs

Today, engineers look for semiconductor solutions that overcome a wide range of common wireless power transfer challenges. First and foremost, engineers require efficient and easy-to-design transmitter solutions. Smart heat management is also essential: it keeps the surface and transmitter at a comfortable temperature and avoids heating the battery of the device that’s charging. A small footprint is highly valued especially for devices that are small in size like wearables. By fitting your designs with a high power rating you can ensure faster charging speed, which will please consumers
