Study shows gallium oxide could enable cheaper power electronics
Researchers from the National Renewable Energy Laboratory (NREL) have modeled the wafer cost of gallium oxide (Ga2O3) semiconductors, and determined the cost could be three times lower than that of silicon carbide (SiC). The finding could lead to lower costs for power electronics such as those used in EVs. The researchers created a bottom-up cost model… Read more »
VisIC publishes reference design for its GaN on-board charger
Israel-based VisIC Technologies, a manufacturer of gallium nitride (GaN) power semiconductor devices for the auto, data center and industrial markets, has published a reference design aimed at the EV industry for its on-board charger (OBC) that uses its GaN technology. The 6.7 kW OBC has a volume of 2.3 liters and weighs 4.5 kg, providing… Read more »
LORD and Scheugenpflug collaborate to scale up EV thermal designs
When EV manufacturers find a high-quality gap filler that maximizes battery performance, they don’t want to hit a snag with the application system. One of the fundamental challenges in designing an EV battery pack is the effective management of heat generated during the battery’s charge and discharge cycles. A basic principle of physics is that… Read more »
Transphorm’s latest GaN transistor passes automotive qualification
Semiconductor provider Transphorm has announced that its third-generation high-voltage gallium nitride (GaN) field-effect transistor (FET) has passed AEC-Q101 stress tests for automotive-grade discrete semiconductors. The transistor targets EV applications including on-board chargers, DC-DC converters, and DC-AC inverter systems. Transphorm’s new FET, the TP65H035WSQA, performed at 175° C during AEC-Q101 qualification testing, which the company says… Read more »
Top circuit protection considerations for DC fast chargers, a new class of high-voltage consumer electronics
DC fast charging isn’t just a godsend for EV drivers looking for a quick charge. It’s also an entirely new level of consumer electronics. “You and I, as members of the general public, have previously never had access to anything higher in voltage than what we see at home in our wall socket,” Tim Patel, Global… Read more »
Sumitomo Electric’s new generation of SiC transistors offer low on-state resistance
Sumitomo Electric’s new V-groove superjunction transistors, which it developed through a joint research project with the National Institute of Advanced Industrial Science and Technology (AIST) use silicon carbide (SiC) semiconductors, and the company claims they offer the lowest on-state resistance yet achieved in an SiC transistor. Sumitomo has already developed V-groove MOSFETs that use a… Read more »
DENSO to produce EV inverters in Maryville, Tennessee
DENSO, an enormous automotive supplier with headquarters in Japan and 220 facilities in 35 countries, plans to produce a next-generation inverter for US OEMs at its plant in Maryville, Tennessee. The Maryville location will be the site of one billion dollars of new investment in electrification, connectivity and safety products over the next few years…. Read more »
Do you have the right level of safety, efficiency and reliability for your EV charging systems?
Sponsored by Littelfuse EV charging stations come in many different types and provide differing speeds (or levels) of charge to a vehicle. Most chargers can be classified into one of two types: AC chargers, which provide alternating current (AC) power to a vehicle’s on-board charger from an electrical utility supply DC chargers, which provide direct… Read more »
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 »
