“STMicroelectronics is dedicated to driving the way forward for electrical mobility and industrial effectivity by our cutting-edge silicon carbide expertise. We proceed to advance SiC MOSFET expertise with improvements within the gadget, superior packages, and energy modules,” stated Marco Cassis, President, Analog, Energy & Discrete, MEMS and Sensors Group. “Along with our vertically built-in manufacturing technique, we’re delivering trade main SiC expertise efficiency and a resilient provide chain to fulfill the rising wants of our prospects and contribute to a extra sustainable future.”
Because the market chief in SiC energy MOSFETs, ST is driving additional innovation to use SiC’s larger effectivity and better energy density in comparison with silicon gadgets. This newest technology of SiC gadgets is conceived to learn future EV traction inverter platforms, with additional advances in dimension and energy-saving potential. Whereas the EV market continues to develop, challenges stay to realize widespread adoption and automobile makers wish to ship extra inexpensive electrical vehicles. 800V EV bus drive methods primarily based on SiC have enabled sooner charging and diminished EV weight, permitting automobile makers to supply autos with longer driving ranges for premium fashions. ST’s new SiC MOSFET gadgets, which shall be made out there in 750V and 1200V lessons, will enhance vitality effectivity and efficiency of each 400V and 800V EV bus traction inverters, bringing the benefits of SiC to mid-size and compact EVs — key segments to assist obtain mass market adoption. The brand new technology SiC expertise can also be appropriate for quite a lot of high-power industrial functions, together with photo voltaic inverters, vitality storage options and datacenters, considerably enhancing vitality effectivity for these rising functions.
Availability
ST has accomplished qualification of the 750V class of the fourth technology SiC expertise platform and expects to finish qualification of the 1200V class within the first quarter of 2025. Business availability of gadgets with nominal voltage scores of 750V and 1200V will observe, permitting designers to handle functions working from commonplace AC-line voltages as much as high-voltage EV batteries and chargers.
Use instances
ST’s Era 4 SiC MOSFETs present larger effectivity, smaller elements, diminished weight, and prolonged driving vary in comparison with silicon-based options. These advantages are crucial for attaining widespread adoption of EVs and main EV producers are engaged with ST to introduce the Era 4 SiC expertise into their autos, enhancing efficiency and vitality effectivity. Whereas the first software is EV traction inverters, ST’s Era 4 SiC MOSFETs are additionally appropriate to be used in high-power industrial motor drives, benefiting from the gadgets’ improved switching efficiency and robustness. This leads to extra environment friendly and dependable motor management, lowering vitality consumption and operational prices in industrial settings. In renewable vitality functions, the Era 4 SiC MOSFETs improve the effectivity of photo voltaic inverters and vitality storage methods, contributing to extra sustainable and cost-effective vitality options. Moreover, these SiC MOSFETs might be utilized in energy provide items for server datacenters for AI, the place their excessive effectivity and compact dimension are essential for the numerous energy calls for and thermal administration challenges.
Roadmap
To speed up the event of SiC energy gadgets by its vertically built-in manufacturing technique, ST is growing a number of SiC expertise improvements in parallel to advance energy gadget applied sciences over the following three years. The fifth technology of ST SiC energy gadgets will function an modern high-power density expertise primarily based on planar construction. ST is on the identical time growing a radical innovation that guarantees excellent on-resistance RDS(on) worth at excessive temperatures and additional RDS(on) discount, in comparison with current SiC applied sciences.
ST will attend ICSCRM 2024, the annual scientific and trade convention exploring the latest achievements in SiC and different large bandgap semiconductors. The occasion, from September 29 to October 04, 2024, in Raleigh, North Carolina will embrace ST technical displays and an industrial keynote on ‘Excessive quantity industrial surroundings for vanguard applied sciences in SiC’.
