GaN Systems exhibits highest-current-rated 650V GaN power transistors at PCIM

In booth 9-507 at PCIM Europe 2019 (Power Conversion and Intelligent Motion) in Nuremberg, Germany (7-9 May), GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) is demonstrating its 650V, 150A GaN power transistor (claimed to be the highest-current 650V GaN power transistor). The GS-065-150 device has 100 times lower switching losses than comparable silicon-based insulated-gate bipolar transistors (IGBTs) it is reckoned, yielding a 99% reduction in switching losses. In addition, a wide range of new products, devices and systems from customers and partners (with many now in production) is also on display.

Recently introduced products at the booth include the GS-065 low-current (3.5-11A) transistor line with EZDrive circuit compatibility. The combination of a smaller, next-generation design and the EZDrive circuit (which eliminates the need for a discrete driver) significantly reduces bill of materials cost and improves performance, says the firm.

Reference tools being shown include the new 50W wireless power amplifier, a small-size, low-cost, and high-efficiency evaluation board suitable for wireless power transfer and charging applications; 1.5kW and 3kW bridgeless totem-pole power factor correction (PFC) reference designs using GaN Systems’ 650V power transistors; and high-performance insulated metal substrate (IMS) half-bridge thermal mounting solutions, which provide design flexibility and scalability with three power level configurations up to 1.5kW, 3kW and 6kW.

Customer demonstrations span industrial, solar, consumer and transportation applications including innovative AC/DC and DC/DC power supplies, energy storage systems, laptop AC chargers as well as high-power wireless charging systems for drones, robots, scooters and 5G applications. The latest innovations in the automotive space include an electric vehicle (EV) onboard charger, traction inverter, and a 480W, 4-channel LiDAR laser-driver.
