Onsemi’s new EliteSiC silicon carbide (SiC) will increase the efficiency and trims the load of Kia’s traction inverters for the corporate’s high-performance fashions, beginning with the EV6 GT.
On the CES present in Las Vegas, semiconductor specialist Onsemi launched a trio of recent SiC gadgets for its EliteSiC household of energy modules. They’re the 1700 V EliteSiC MOSFET and two 1700 V avalanche-rated EliteSiC Schottky diodes.
The 1700 V EliteSiC MOSFET delivers larger breakdown voltage (BV) SiC options, required for high-power industrial purposes. The 2 1700 V avalanche-rated EliteSiC Schottky diodes enable designers to attain steady high-voltage operation at elevated temperatures whereas providing excessive effectivity enabled by SiC.
“By offering best-in-class effectivity with lowered energy losses, the brand new 1700 V EliteSiC gadgets reinforce the excessive requirements of superior efficiency and high quality for merchandise in our EliteSiC household in addition to additional broaden the depth and breadth of Onsemi’s EliteSiC,” stated Simon Keeton, govt vp and common supervisor, Energy Options Group, Onsemi.
Within the Kia EV6 GT, Onsemi’s high-power density SiC energy module minimizes parasitic losses and thermal resistance with strong bundle reliability utilizing revolutionary interconnects. This results in lowered energy losses related to DC-to-AC conversion together with lowered dimension and weight of the traction inverter. These advantages mix for a promised 5 % improve in EV driving vary.
“Our collaboration with Hyundai Motor Corp./Kia is rooted within the superior efficiency of our EliteSiC know-how,” stated Simon Keeton, govt vp and common supervisor, Energy Options Group, Onsemi. “As vital is our shortly rising, vertically built-in SiC provide chain that permits Onsemi to plan for the mandatory scale to assist high-volume manufacturing for EVs.”
Inside the traction inverter of the EV6 GT, the EliteSiC energy module permits high-efficiency energy conversion from the DC 800 V of the battery to the AC drive for the rear axle. Partly because of the effectivity of the Onsemi SiC modules, the EV6 GT mannequin accelerates from zero to 60 mph in 3.4 seconds and reaches high velocity at 161 mph.
The EV6 GT is barely the primary of a line of upcoming high-performance Hyundai and Kia EVs constructed on Hyundai’s Electrical – World Module Platform (E-GMP), in line with the businesses.
