USCi technology and products enable affordable power efficiency in key markets that drives a new and greener economy.

USCi technology and products are uniquely positioned to leverage the lower cost of outsourced manufacturing capabilities in silicon carbide substrates, epitaxy, and foundries for production device fabrication. This dynamic is what continues to fuel the growth of Digital and Analog IC’s and the time is now for Silicon Carbide (SiC). This advancement for SiC will create lower cost of goods, better continuity of supply, and improved quality for these demanding markets.


The properties of Silicon Carbide (SiC) devices are perfect for next generation electric cars and trains. This is the largest market potential for SiC devices. The use of high voltage electronics is a necessity in future automobiles as the use of electric drives lessens our dependency on fossil fuels. SiC devices will be used in all applications in these vehicles and this market alone will grow to over $400M in the coming years.

A specific automotive application example is the battery to bus Boost Converter. Using SiC transistors and diodes improves the efficiency, reduces the size of passive components and weight by up to 50%.
Using SiC transistors and diodes in the powertrain allows for increased switching frequency and reduces cooling. This reduces a significant amount of cost, additional weight, and space in the vehicle.
The higher voltage and higher power electrical requirements for trains are a great fit for SiC devices. The performance of SiC at high voltage is well suited to improve the electronic systems for rail transportation. USCi has industry leading experience in large die size and high voltage SiC capability that enables the use of wide band gap adoption into high power modules and systems.

Power Conversion & Supply

Silicon Carbide (SiC) devices are widely used in Power Conversion applications such as AC/DC power supplies, PFC and UPS. Initially, this was primarily in high performance products, but now with the demand for better efficiency SiC is making its way to standard products that are used in many computing and consumer applications.

Organizations such as Climate Savers™, Energy Star™, and Greengrid™ are making energy efficiency a requirement rather than an option. SiC devices are becoming an easier choice for OEMs.
A typical application for SiC devices is in active power correction, especially in power supplies with a high output power rating typically used in Servers and Datacenters.

Military, Aerospace, & Well Logging

The properties of Silicon Carbide (SiC) over temperature are ideal. The same cannot be said for GaN or silicon products. When designers need the best performance over extreme temperatures they look at SiC based products that operate in excess of 250 °C.

Applications such as Well Logging, Aerospace, and Military electronics have been designing in SiC devices for years. These applications will increase the use of SiC as performance and availability continues to improve.

Power Generation

The use of Silicon Carbide (SiC) devices in Solar and Wind applications has arrived. Converting from Si to SiC allows for significant improvement in efficiency and enables the use of active intelligent HV power conversion. Another trend in the market is the move to higher grid tied voltages and SiC is a critical component in making that trend a reality.

Data from 3rd parties such as the Fraunhofer Institute ISE in Germany have shown results of solar inverters reaching > 99% efficiency as compared to 95% or less with standard silicon components. As the footprint of Solar Inverters, Solar Micro-Inverters, and Wind Power increases around the world, these percentage gains in efficiency at each node can translate into GIGAWATTS of power savings on the grid.
