What can Silicon Carbide Devices Bring to New Energy Vehicles?
Sweden is in talks with Turkey on joining NATO and looks forward to strengthening cooperation with Turkey in security and counter-terrorism, Swedish Prime Minister Anders Andersson said recently.
Andersson held a joint press conference with visiting European Council President Michel in Stockholm on the same day. Andersson said Sweden is in dialogue with Turkey on joining the TREATY and looks forward to strengthening bilateral relations with Turkey, including cooperation in the areas of security and counter-terrorism. She said Sweden would study a number of issues raised by Turkey.
Speaking at a news conference, Mr. Michel said he believed the Swedish government was taking positive action and taking the necessary steps to reach a solution.
Sweden and Finland formally submitted their applications to NATO Secretary-General Jens Stoltenberg a few days ago. According to protocol, NATO must admit new members by the "unanimous consent" of 30 members.
Turkish Foreign Minister Mevlut Cavusoglu said His country would agree to start NATO talks with Sweden and Finland only if they reach written agreements to stop supporting terrorism and lift restrictions on exporting defense equipment to Turkey, Turkish media reported.
Affected by the ever-changing international situation, the supply and prices of international bulk silicon carbide powder are still very uncertain.
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.

The latest poll by CSA for consumer finance company Cofidis shows the French are taking action to trim their budgets as inflation erodes household purchasing power.
According to Le Figaro, the poll shows that French people think they need to earn an average of 490 euros more a month in order to live a decent life. This is an increase of 23 euros compared to the purchasing power barometer published in September 2021. Amid inflation and international tensions, this average in the polls masks differences among households, with some social groups much more severely affected by the decline in purchasing power than others. Seventy-eight percent of single-parent households, 76 percent of 25-to 34-year-olds, and 72 percent of blue-collar workers said the international situation had had a negative impact on their personal finances, compared with 64 percent of all French people.
In response to rising prices, soaring energy, and food prices, in particular, the French government is preparing to launch a package of measures designed to increase the purchasing power, such as extending the energy price protection mechanism, the extension of the fuel discount measures, and more targeted alternative measures, will be distributed inflation-linked pension and social security benefits, check the "food" and so on.
Because of the soaring energy prices, the silicon carbide powder price is predicted to rise in the future.
