GaN Systems unveiled two wireless power amplifiers that will revolutionize the wireless charging market for high-power consumer, industrial, and transport applications. These new solutions include the 100 W power amplifier with ranges from 70 W to 100 W and the 300 W power amplifier with ranges from 150 W to 1 kW. GaN Systems displayed both solutions and demonstrated the 300 W amplifier at PCIM in Nuremberg, Germany, June 5-7, 2018 in Booth 511 in Hall 9 (9-511).
As wireless charging goes mainstream, GaN (gallium nitride) is removing the limitations by making way of new higher power system designs that provide the spatial freedom and faster charge times.
- The 100 W power amplifier [GSWP100W-EVBPA] is ideal for applications in the consumer market for items such as laptop computers, recreation drones, domestic aide robots, power tools, and fast-charging of multiple smart phones.
- The 300 W power amplifier [GSWP300W-EVBPA] is targeted for the industrial and transportation markets for applications that include delivery drones, warehousing robots, medical units, factory automation, contractor power tools, eBikes, and scooters.
Both power amplifiers have a range of features including current or voltage control, built-in protection circuitry, EMI filtering, and configurable output power. The amplifiers combine GaN systems power transistors with high frequency GaN E-HEMT drivers from pSemi.
“Our GaN solutions are creating opportunities for the development of high-power, high efficiency power systems in applications such as wireless power transfer and charging,” stated Paul Wiener, Vice-President, Strategic Marketing for GaN Systems. “The power ecosystem has changed. There is now availability of high dv/dt level-shifters, fast response IC sensing and control, low-loss high frequency magnetics, and high performing GaN transistor and amplifier capabilities that are enabling smaller, lighter, lower cost, and more efficient power systems.”
