Know the Power of Silicon Carbide

In both the automotive and industrial markets the adoption of energy solutions with SiC materials is accelerating on a high level. Compared to making silicon wafers, making silicon carbide SiC wafers is a far more involved process and with the rising demand for SiC devices, companies that prepare them to have to nail down sources of SiC wafer.



This is important because for a variety of power components and devices used in renewable energy, electric vehicles, fast-charging stations, and various industrial applications the properties of SiC are very well-suited.

In terms of energy SiC offers several benefits, which is why in the development of the new power electronics, it has been and will be the focus of attention together with its cousin GaN.

Compared to typical silicon, SiC can withstand substantially higher voltages, up to ten times higher. This indicates that in high-voltage electronics applications fewer series components should be used that result in reducing complexity and system costs. You will come across the SiC wafer supplier too.

In the semiconductor industry, SiC SBDs are already replacing silicon. In specific markets, GaN could be a strong competitor. There has been a drastic reduction in recovery losses with Inverters having SBDs, resulting in improved efficiency. Several requirements need to be kept in mind by the power design, including space and weight, which play a significant role in inefficiency.

To power factor correctors (PFC) circuits and secondary side bridge rectifiers in switching mode power supplies SiC-SBDs are increasingly applied. In the portfolio of Rohm SiC-SBDs, 600V and 1,200V modules are included, with an amperage rating range from 5A to 40A.

The full quality of a semiconductor does not get exploited by the efficiency of conventional power electronics but only with a loss of about 15% of efficiency in the form of heat. The SiC semiconductor material has great potential to meet the requirements of these market trends because of its physical properties so they are used by SiC wafer manufacturer.



There is an increase in switching frequency by low switching losses and a reduction in component size is seen. With the increase in frequency, the size reduction is more or less proportional.
