Using SiC FETs in solar inverters and energy storage

The design of a renewable energy inverter involves many tradeoffs, including cost, electrical specifications, efficiency, features, reliability, installation cost, etc. Adding to these assorted considerations is the radically improved performance of SiC versus silicon-based semiconductors and their cost differences, which makes evaluating various topology options like comparing apples to oranges and pears. Models for efficiency, cost, and reliability are needed to optimize tradeoffs and to dependably predict their overall effects.

 

Solar Inverters and Energy Storage

Using SiC devices in inverters improves efficiency and ultimately power production thanks to the 50% lower power switching losses, 3x-5x switching frequency, and lower conduction losses when compared to Si-based technology.
