element14 has announced the availability of Nexperia’s newest and innovative Power Gallium Nitride (GaN) FET range that can deliver improved density and efficiently use power in a small form factor, enabling the development of efficient systems at a lower cost, and providing the potential to transform power performance in electric vehicles, 5G communications, IoT and more. This innovative range also provides solutions to design engineers looking to reduce Co2 and move towards increased electrification.

Delivering wide benefits

GaN technology helps overcome many limitations of existing technologies, such as silicon-based IGBTs and SiC for delivering direct and indirect performance benefits to a range of power conversion applications. Concerning electric vehicles, GaN technology helps reduce power losses that can impact the range of a vehicle. More efficient power conversion also reduces the need for cooling systems that dissipate generated heat, reducing the vehicle’s weight and system complexity. This in turn also leads to a longer operating range of a battery. Power GaN FETs are also well positioned for applications in data centres, telecom infrastructures, and industrial applications.

GaN FETs deliver superior performance in solutions such as hard switching for AC-DC Totem pole PFC applications, LLC phase-shift full-bridge (resonant or fixed frequency) for soft-switching applications, all DC-AC inverter topologies and AC-AC matrix converters using bidirectional switches.
