Cost-Effective High-Voltage Power Chips for Renewable Energy Grids

energyTestedTRL 5

Imagine the electrical switches in a power grid as faucets. Standard silicon switches are like old, bulky valves that leak energy and take up too much space. This project creates a new material called Silicon Carbide that acts like a high-performance, compact valve, allowing electricity to flow more efficiently with much less waste.

The business problem

What needed solving

High-voltage Silicon Carbide (SiC) devices are currently too expensive for widespread use in energy grids. This cost barrier prevents the adoption of smaller, more efficient converter stations for wind and solar energy.

The solution

What was built

Developed 3.3kV and 6.5kV SiC MOSFETs, a specialized gate driver circuit, and a Half Bridge Power Module design with optimized thermal cooling.

Who can put this to work

Wind Energy
enterprise
Target: Wind turbine manufacturer

If you are a turbine manufacturer dealing with bulky and expensive converter stations — this project developed high-voltage SiC MOSFETs that reduce die costs by 20%. This allows for smaller converter footprints and lower overall system costs.

Solar Energy
mid-size
Target: Solar inverter producer

If you are an inverter producer dealing with high energy losses in large-scale plants — this project developed 3.3kV and 6.5kV devices. These improvements help lower the Levelized Cost of Energy (LCoE) for solar installations.

Electrical Grid Infrastructure
enterprise
Target: Grid operator or equipment supplier

If you are a grid supplier dealing with slow or inefficient circuit breakers in DC stations — this project developed solid-state circuit breakers (SSCBs). These use SiC technology to handle fast transients more reliably than traditional silicon-based IGBTs.
