onsemi introduced that China-based EV maker NIO selected the newest VE-Trac Direct SiC energy modules from onsemi for its next-generation electrical autos (EVs). The silicon carbide (SiC)-based energy modules allow longer vary, increased effectivity and sooner acceleration for EVs.
The collaboration of the 2 firms is expediting the commercialization of SiC applied sciences to carry EVs geared up with superior semiconductor materials to the market.
On the coronary heart of an EV, the principle traction inverter converts battery vitality into giant quantities of torque and acceleration. The VE-Trac Direct SiC is an built-in single-side direct cooling (SSDC) energy module in a six-pack configuration with a low activate resistance of 1.7 mΩ.
This platform implements the second technology SiC MOSFET know-how from onsemi to attain new ranges of efficiency, effectivity, and high quality whereas sharing a suitable package deal footprint with its IGBT predecessor. An built-in pin fin baseplate allows direct liquid cooling and simple meeting which permits most energy output and extra environment friendly thermal dissipation.
From all of the options we thought-about, the VE-Trac Direct SiC traction energy modules supplied the perfect effectivity throughout testing, permitting us to increase our New European Driving Cycle (NEDC) vary by 4% in comparison with the present silicon answer. onsemi satisfied us with the excessive efficiency and reliability of its merchandise in addition to the superb help from its engineering and administration staff. We stay up for collaborating with onsemi on bringing extra modern EVs to marketplace for generations to return.

The VE-Trac choices, together with beforehand launched VE-Trac Twin and VE-Trac Direct platforms, can be found in silicon-based IGBT and in SiC with varied voltages, and for traction inverter energy starting from 100 to 250 kW. With its standardized mechanical footprints and expanded energy rankings, the VE-Trac product household is designed to scale EV energy outputs, accelerating the adoption of hybrid and battery EVs (BEV).
This design collaboration is the fruits of considerable efforts onsemi has put into growing the correct applied sciences for rising purposes reminiscent of good EVs. onsemi is the one provider of silicon carbide options with vertical integration functionality together with SiC boule development, substrate, epitaxy, machine fabrication, best-in-class built-in modules and discrete package deal options. We’re quickly increasing our SiC capability and are uniquely positioned to handle the rising EV market with provide assurance, efficiency, high quality and tailor-made SiC finish options.
