Black Carborundum

Black rainbow carborundum Description

Advantages of silicon carbide (SiC).

The first is the increase in power density: as we all know, the space inside a car is very small, so the increase in power density is the future development trend. The characteristics of SiC devices can not only make the power semiconductor package smaller compared to silicon solutions, but also make Passive components and heat sinks matching power devices are made smaller.

The second is the improvement of system efficiency: for example, when used in the main inverter, using SiC modules can improve the system efficiency by about 5% compared with IGBT modules. Then the OEM has two options: first, use the same The battery capacity is higher, and the cruising range can be increased by 5%;

Second, if the same cruising range is designed, the battery capacity can be reduced by 5%. For example, Model 3 has a battery of about 80 kilowatt-hours, and 5% is 4 kilowatt-hours of electricity. At present, the cost is calculated at about RMB 700-1,000 per kilowatt-hour of electricity. The cost savings are quite considerable. Of course, the SiC module must be taken into account. It will be more expensive than IGBT.

Finally, SiC has another important advantage, which is that it is very suitable for high-voltage applications. We have seen that some mainstream car manufacturers have increased the battery voltage of their cars to 800V. In the future, high-voltage DC charging piles will also use high voltage. In these high-voltage applications, SiC, especially high-voltage 1200V silicon carbide, will be more efficient than silicon. There are advantages.
