The wireless power market
Wireless charging eliminates the need for cords, connectors and electrical
plugs and allows any user with a compatible device to use the same wireless
charging pad. Users simply place the portable device on the charging surface to
complete the wireless connection.
In terms of unit deployment, the consumer wireless power market is still in
its infancy. As new design options for smaller and cheaper solutions become
available, the adoption rate for mobile and consumer electronics will increase
significantly. Within the next 2 years, the installed base for wireless charging
enabled devices is forecasted to exceed 100 million units.
Foreign Object Detection and safety features
System safety for wireless charging, as with any power transfer system, is a major concern.
Typically, such wireless power transfer systems are required to have Foreign Object Detection (FOD), e.g.,
to prevent heat generation in metal objects that are accidentally placed on the power transmitter, and (ii)
communication between transmitter and receiver for to control the transferred power level and detection of
exceptional power losses in the channel. In addition the temperature of the charger is measured to ensure
that system temperature will not exceed a defined maximum safety level. The required FOD level and safety is depending on the transmitted power, use case and wireless charging standard.
The level of required FOD detection and safety is depending on power level, use case and wireless
The market adoption of wireless charging will be determined by the availability of worldwide mature
standards, and the availability of simple to use and affordable charging products. Developing
flexible hardware solutions can help to reach this goal. Adding application expertise and system
enhancements beyond simple charging can improve the user experience and therefore help to drive the
demand for these new technologies. Smart Wireless Charging solutions enable Secure Connections for a Smarter World.
