Magnetic Resonance Wireless Power Solutions
IDT leverages its wireless power expertise to develop solutions for magnetic resonance-based applications (also known as a resonant transformer, resonant-inductive coupling, or resonance charging). Magnetic resonance solutions transfer power between two inductors that are tuned to the same natural resonant frequency. Resonance power technology allows power to be transferred wirelessly over a distance with flexibility in relative orientation and positioning.
Alliance for Wireless Power (A4WP)
IDT is a sponsor member of the A4WP, an independently operated organization composed of global wireless power and technology industry leaders. The A4WP will focus on a new wireless power transfer technology that provides spatial freedom for charging of electrical devices in cars, on table tops and for multiple devices simultaneously.
In addition, IDT has partnered with one of the A4WP’s founding members, Qualcomm, to be a silicon vendor for Qualcomm’s WiPower devices. These ICs will be designed to meet the requirements of Qualcomm’s new near-field magnetic resonance wireless power charging solution that is designed to provide spatial freedom for charging consumer electronics, such as mobile phones and other battery-powered/low-power direct-charge devices. See press release here.
Intel® Wireless Charging Technology (WCT)
IDT has partnered with Intel to be sole silicon vendor for Intel’s WCT reference designs for PCs and peripherals. Wireless charging ICs by IDT will provide industry-leading size and cost reduction, while simplifying product development and integration. Intel, along with IDT, aims to deliver validated reference designs that are targeted for deployment in Ultrabooks™, all-in-one (AiO) PCs, smartphones, and standalone chargers.
About Resonance Power Technology
Resonance power technology is the near-field wireless transmission of electrical energy between two coils that are tuned to resonate at the same frequency. Based on the principles of electromagnetic coupling, resonance-based chargers inject an oscillating current into a highly-resonant coil to create an oscillating electromagnetic field. A second coil with the same resonant frequency receives power from the electromagnetic field and converts it back into electrical current that can be used to power and charge a portable device. Resonance charging offers unique advantages in spatial freedom, enabling the transmitter (resonance charger) to be separated from the receiver (portable device) by several inches or more.
