NuCurrent partners with GaN Systems to expand wireless charging

April 13, 2018

Chicago, IL. NuCurrent has announced the development of 150-W wireless power solutions designed for industrial and consumer applications. This development, in partnership with GaN Systems, builds upon NuCurrent’s achievements in wireless power and wireless charging, including the development of thin and efficient 15-W wireless-charging antennas for smartphones.

“We’re excited to bring these new high-power solutions to market,” said NuCurrent VP of sales and marketing Tim Tumilty. “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. Our new solutions solve the most important challenges for product categories that need 150 watts or more.”

Smartphones and small electronic devices typically require less than 15 watts of power and are suited for silicon-based transistors. However, for wireless charging applications with power needs of 150 watts or more, existing silicon-based transistors can heat up and become inefficient. To address this challenge, NuCurrent selected a 150-W 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,” said GaN Systems vice president 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.”

Demonstrations of the 150-W wireless charging solutions will be available at the upcoming Power Conversion and Intelligent Motion (PCIM) conference June 5-7 in Nuremberg, Germany.
