Multi-Directional Wireless Power for Electrical Applications
- Field
- Electronics
- Patent
- IP00477
Key Problem and Market Opportunity
- First demonstrated by Nicola Tesla in the 1890s, applications of Wireless Power Transfer (WPT) are gaining popularity and in particular for charging everyday consumer electronic devices
- It provides simplicity and convenience without the need of manipulating any electric connectors or the associating wiring
- Existing WPT systems usually require proper alignment of the power transmitters and the receivers, otherwise transfer efficiency will be greatly reduced
- The WPT technology market was valued at US$ 2.5B in 2016 by MarketsandMarkets1

Key Advantages of the Technology
- By intelligently controlling the phase angles and amplitudes of voltage/current flowing through the coils of the omni-directional transmitter, the direction and magnitude of power transfer could be controlled directly
- detect load positions and provide the corresponding power transfer wirelessly at the needed directions to avoid energy wastage
- relax alignment requirement for transmitter and receiver circuits
- Continuous transfer of power to electrical loads even in motion
