In partnership with GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications), Chicago-based firm NuCurrent has developed 150W wireless power systems designed for industrial and consumer applications with high power needs. This builds on NuCurrent’s achievements in wireless power and wireless charging, including what is claimed to be the thinnest and most efficient (highest Q) 15W wireless charging antennas for smartphones.

“Following the rapid adoption of wireless charging for devices that need a few watts of power, customers are demanding solutions that deliver higher levels of power,” says NuCurrent’s VP of sales & marketing Tim Tumilty. “Our new solutions solve the most important challenges for product categories that need 150W or more.”

Smartphones and small electronic devices typically require less than 15W of power and are well suited for silicon-based transistors. However, for wireless charging applications needing 150W or more, existing silicon-based transistors can heat up and become inefficient. To address this challenge, NuCurrent selected a 150W gallium nitride-based power amplifier from GaN Systems.

“These solutions open up wireless charging to new categories like power tools, autonomous robots, drones, and more,” says GaN Systems’ VP strategic marketing Paul Wiener. “With NuCurrent’s technology and system design capabilities and our high-power transistor and amplifier capabilities, the possibilities for wireless charging at high power levels have been expanded in some really important directions,” he adds.

Demonstrations of the 150W wireless charging solutions will be given in booth #511 (hall 9) at the Power Conversion and Intelligent Motion (PCIM 2018) conference in Nuremberg, Germany (5-7 June).
