2 inch Silicon Carbide Wafers 6H or 4H N-type or Semi-Insulating SiC Substrates

Short Description:

Silicon carbide (SiC), also known as carborundum, is a semiconductor containing silicon and carbon with chemical formula SiC. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, or both.SiC is also one of the important LED components, it is a popular substrate for growing GaN devices, and it also serves as a heat spreader in high-power LEDs.

1. 5G infrastructure -- communication power supply

Communication power supply is the energy base for server and base station communication. It provides electric energy for various transmission equipment to ensure the normal operation of communication system.

2. Charging pile of new energy vehicles -- power module of charging pile

The high efficiency and high power of the charging pile power module can be realized by using silicon carbide in the charging pile power module, so as to improve the charging speed and reduce the charging cost.

3. Big data center, Industrial Internet -- server power supply

The server power supply is the server energy library. The server provides power to ensure the normal operation of the server system. The use of silicon carbide power components in the server power supply can improve the power density and efficiency of the server power supply, reduce the volume of the data center on the whole, reduce the overall construction cost of the data center, and achieve higher environmental efficiency.

4. Uhv - Application of flexible transmission DC circuit breakers

5. Intercity high-speed rail and intercity rail transit -- traction converters, power electronic transformers, auxiliary converters, auxiliary power supplies
