GaN Systems has released two power amplifiers for the high power wireless charging market. These new solutions include a 100 W power amplifier with ranges from 70 W to 100 W and a 300 W power amplifier with ranges from 150 W to 1 kW. GaN Systems showcased both the solutions and demonstrated the 300 W amplifier at PCIM in Nuremberg, Germany from June 5-7.
As wireless charging goes mainstream, GaN (gallium nitride) is removing the limitations by making way for 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, e-Bikes, 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.
