PowerSphyr Inc of Danville, CA, USA – which delivers end-to-end wireless power charging solutions – and GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) have announced a strategic agreement to bring GaN-based wireless power systems to market for high-powered applications spanning consumer, industrial and automotive sectors worldwide.

Working together to develop hardware and firmware solutions, the firms aim to deliver solutions that adhere to wireless charging standards, while developing next-generation power and functional capabilities that exceed anything offered in the market currently. PowerSphyr supports the three key industry standards for wireless power charging: magnetic induction; magnetic resonance; and RF energy harvesting.

GaN Systems says that gallium nitride transistors are the best means for higher-power-level applications from 30W up to several kilowatts – much greater than achieved with traditional silicon solutions and providing the building block to achieve higher power, higher efficiency and lower cost in wireless power transmitters. GaN-based wireless power solutions have enabled faster charging, higher power transfer and new system designs that are removing the limitations of distance and power, and moving charging beyond phones into applications including power tools, robots, drones and ebikes.

“We selected GaN Systems on the basis of our strategic vision for delivering fast, flexible and complete wireless charging solutions, and their ability to rapidly deliver a complete family of robust, reliable, best-in-class semiconductors,” says PowerSphyr’s CEO & chairman Neil Ganz.

“Cutting the cord began with the telephone then ethernet LAN and now the power cord,” comments GaN Systems’ CEO Jim Witham. “A world without cords is becoming a realization because of collaboration with visionary companies like PowerSphyr, whose technology, approach and expertise is uniquely positioned to accelerate the wireless power transfer and charging marketplace.”
