Get Witricity (Wireless Power Transmission) - Docs Neu Edu

WiTricity's technology allows wireless power transfer over distance via magnetic resonance. Alternating current (AC) electricity runs through an electromagnetic coil within a charging station to form an oscillating electromagnetic field.

We aim to expedite factory processes and reduce running costs by delivering wireless power transfer systems that enable automatic re-charging. With its magnetic resonance technology, WiTricity is uniquely able to enable us to create highly flexible and efficient solutions.”

The secret to how wireless charging works is electromagnetic induction: A transmitter coil in the charging base sends out a signal. The signal searches for a receiver coil, like the one in your compatible smartphone.

Disadvantages of WiTricity: The resonance condition should be satisfied and if any error exists, there is no possibility of power transfer. If there occurs, a very strong ferromagnetic material presence, then there may be a possibility of low power transfer due to radiation.

This wireless power demonstration system jointly developed by EPC and WiTricity is a class-D power system operating at 6.78 MHz, and capable of delivering up to 15 W to a load.

WiTricity has developed systems/devices that use Magnetic Resonance to couple energy through oscillating magnetic fields. Resonant coupling occurs when the operating frequencies of the two systems – a transmitter and a receiver — are approximately the same.
