Wireless Power Transmission holds the promise of freeing us from the domination of power cords. The technology is increasingly being incorporated into various electronic devices. Different wireless technologies exist for both near-field and far-field communications. These include inductive, RF, resonant, ultrasound and infrared charging. These are governed by various standards and their associated trade-offs. As consumers warm up towards a world without cables, the wireless power transfer technology is positioned to explode.
What is Wireless Power Transmission?
As you may have already guessed, the wireless power transmission allows electrical devices to be charged continuously without a power cord. The technology is improving continually. Wireless power transmission is increasingly implemented by the manufacturers across various industries. Though the full potential of the idea has not been explored yet, extensive research has led to the conclusion that wireless power transfer is possible.
Are you wondering how the wireless power works?
It is based on the basic concept that most of the engineers are aware of – Law of Induction proposed by Faraday. The changing magnetic field can produce an AC current. Wireless power transmission involves two coils – a transmitter and a receiver. These coils act as inductors and can be considered to be a transformer without a core. Essentially, these are two inductively coupled air coils.
Advantages of Wireless Power
There are several advantages of wireless power transfer:
- Wireless power enables you to seal your device completely. So, wireless power can be your perfect solution whether you are looking to get rid of the power port, or wish to advance your product from water-resistant to waterproof.
- Using wireless power means less cord clutter and it provides one universal, cordless power solutions for all the electronic devices.
- It offers a multitude of practical applications with the power transfer of 0 to 200W. The level of efficiency of wireless power transmission is thus very high.
- It also increases the product life by eliminating the physical limitations of connectors. Thus, wireless power provides a more robust product to the manufacturers.
The Future of Wireless Power
Wireless power transmission is still in its early period of development and implementation. The market for WPT began in 2012 at a very small scale and comprised mainly of consumer applications. By the year 2022, wireless power is expected to achieve an aggressive growth of over $5 billion. The technology will dominate the consumer market and is also expected to expand to the industrial and automotive markets.
Applications of Wireless Power Transfer
All wireless power transmission technologies are under active research, mainly focused on maximizing the power transfer efficiency and investigating techniques for magnetic resonant coupling. There are several ambitious projects in place which also includes the idea of walking into a room equipped for WPT and having your electronic devices charge automatically.
There are numerous applications of WPT. It can provide power from an AC source to compatible devices and batteries without any physical connections. WPT can help recharge mobile devices, drone, cars and other transport equipment.
There has been the exciting development of WPT, in the consumer electronics market. Electric buses are becoming a norm across the globe and many European countries are planning for wireless charging. Various companies are developing cordless kitchen appliance, cordless power drills for construction sites, integrated furniture and lighting for completely wireless homes, and many more devices. Thus, WPT works everywhere.
The wireless power transmission is at the forefront of electronic product development these days. The wireless power transfer methods which are already used in the electronic devices provide highly flexible means to charge batteries of power-hungry devices. Wireless power designs can address the growing market demands for greater mobility and extended operation without corded power.
