GaN Systems makes available high-efficiency 50W wireless power amplifier evaluation kit

GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) has announced the availability of its 50W wireless power amplifier, a small-size, low-cost and high efficiency evaluation board suitable for wireless power transfer and charging applications. It is targeted for lower-power applications in industrial and consumer markets for items such as power tools, Internet of Things (IoT) devices, handheld terminals, medical devices and household robots.

The evaluation kit adds to GaN Systems’ solutions that include the 100W power amplifier and 300W power amplifier, which are designed to support, simplify and speed up the innovation of wireless power transfer systems. These kits combine GaN Systems’ power transistors with high-frequency GaN E-HEMT drivers from pSemi Corp and are designed to be consistent with AirFuel standards.

“Wireless power is growing, and technologies need to progress quickly to overcome the current technical challenges in the market,” says Paul Wiener, VP strategic marketing. “In the area of wireless power transfer, designers are demanding solutions with spatial freedom, high power and high efficiency which, by definition, requires high-frequency GaN-based solutions.”

The 50W evaluation kit addresses challenges associated with working at high frequency, which provides an easy-to-use baseline for engineers in their system designs, says the firm.

GaN Systems is displaying its family of wireless power amplifiers and several wireless power implementations in booth 553 at the Applied Power Electronics Conference (APEC 2019) in Anaheim, CA, USA (17-21 March).
