STMicroelectronics and Leti to enhance on-board charging with gallium nitride

Semiconductor provider STMicroelectronics and French research institute Laboratory of Electronics and Information Technologies (Leti) have announced plans to enhance on-board EV chargers with gallium nitride-on-silicon (GaN-on-Si) technology. They plan to have validated engineering samples ready in 2019. Devices that use gallium nitride can handle higher voltages, frequencies and temperatures than those using conventional materials such… Read more »

Gallium nitride power diode shows near-ideal performance in all aspects simultaneously

Silicon-based semiconductors are approaching their performance limits, so researchers are investigating materials such as gallium nitride (GaN) as potential replacements. A team of engineers from Cornell, Notre Dame and the semiconductor company IQE has created GaN power diodes capable of serving as the building blocks for future GaN power switches. Alas, GaN is prone to… Read more »

Developer of gallium nitride power switching semiconductors raises $20 million

GaN Systems Inc., a developer of gallium nitride power switching semiconductors, has closed a $20-million Series C financing round. The company will use the new money to ramp up sales and marketing efforts and to continue expanding its manufacturing line.

Cree to supply SiC semiconductors to ZF for electric drives

Cree, a US maker of silicon carbide (SiC) semiconductors, has partnered with German parts supplier ZF Friedrichshafen to supply SiC semiconductors for electric drives. ZF will initially use Cree’s technology to fulfill pre-existing orders from several auto manufacturers for silicon carbide-based electric drives, but ZF hopes to make silicon carbide electric drivelines available to the… Read more »

Transphorm introduces second 900 V GaN FET for three-phase applications

Transphorm, a provider of Gallium Nitride (GaN) semiconductors, has introduced its second 900 V Field-Effect Transistor (FET), the Gen III TP90H050WS. Transphorm’s devices now enable three-phase industrial systems and higher voltage automotive electronics to use GaN. The FET has a typical on-resistance of 50 mOhm with a 1000 V transient rating, offered in a standard… Read more »

SiC vs GaN semiconductors for EV power converters: Tech Opinion

Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
