Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.
Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the silicon carbide powder market.
What is Silicon Carbide SiC?
Silicon carbide (SiC) is a hard compound containing silicon and carbon. A semiconductor, it is found in nature in the form of the extremely rare mineral moxanite.
It has been mass-produced in powder and crystal form since 1893 for use as an abrasive. Silicon carbide particles can be sintered together to form very hard ceramics that are widely used in applications requiring high durability, such as ceramic plates in car brakes, car clutches, and bulletproof vests. Large silicon carbide single crystals can be grown by the Lely method, and they can be cut into gemstones called synthetic mossanes.
What can Silicon Carbide Devices Bring to New Energy Vehicles?
Silicon carbide power devices have been used in critical power systems inside electric vehicles, including traction inverters, on-board chargers (OBC), and DC-DC converters. Key advantages over traditional silicon devices include higher voltage and higher frequency features, resulting in higher system efficiency, faster switching, lower losses, and better thermal management. Compared with silicon-based devices, silicon carbide devices have the following advantages:
The use of silicon carbide devices can make the driving motor bear more input power at low speed, and because of its high thermal performance, not afraid of the thermal effect and power loss caused by excessive current. When the vehicle starts, the driving motor can output more torque and obtain stronger acceleration ability.
SiC devices can reduce the loss through two dimensions of conduction/switching, so as to achieve the purpose of increasing the range of electric vehicles. The results show that the turn-off loss of sic-MOS is about 20% of that of Si-IGBT at 25°C junction temperature. At 175°C junction temperature, the turn-off loss of sic-MOS is only 10% of that of SI-IGBT. In general, the use of SiC devices in new energy vehicles can increase the driving range by 5-10%, and the average driving range is more than 600 kilometers.
High rated voltage
Silicon carbide MOSFET has a higher voltage rating, making the technology suitable for EV applications and EV quick charging infrastructure. More importantly, the SiC can be replaced directly without major changes, enabling rapid development while keeping the BOM low.
To achieve lightweight thanks to the superior performance of SiC, SiC devices can achieve the effect of reducing the volume in the following aspects:
1, the package size is smaller, and the average weight is reduced by 150 to 200 kg;
2, reduce the use of filters and passive devices such as transformers, capacitors, inductors, etc.;
3, reduce the radiator volume.
At present, the price of SiC devices is 4-6 times that of silicon based devices, but the use of SiC devices to achieve a substantial reduction in battery cost and the improvement of the range, reducing the overall cost of the vehicle.
