#One choice in SiC power modules

The worlds industries are growing fast and the demand of innovative and reliable technologies is increasing. Technical requirements of tomorrow will not be the same as they are today. 

SiC opens up a lot of possibilities for costs-, size- and performance improvements at system level. This is especially true for high-switching frequency applications. However, implementation of SiC comes with several challenges requiring best-in-class packaging.

To make the most out of SiC, it requires:

  • Customized, low-inductive package and pin-out allowing high switching speeds

  • Advanced bonding and joining technology (Danfoss Bond Buffer®) 

  • Dedicated cooling technology (ShowerPower®)

FAQs

Engineering SiC power modules can be challenging. To overcome the challenges, experience in electrical, thermal and mechanical design is key. Utilize our proven SiC track record and work together with our application experts to take your SiC application to the next level. 

What are the benefits of SiC?
  • Highest efficiency
    SiC offers highest efficiency due to reduced switching losses.

  • Power density
    Excellent output power and power densities are reached in combination with high switching frequencies, minimal losses and maximum efficiency.

  • Lower overall system costs
    The increase in switching frequency means passive filter components can be drastically reduced. Power losses are reduced at the same time, resulting in smaller heat sinks and reducing cooling needs in general. Both benefits result in a major decrease in overall system costs.
What are the main SiC design challenges?

Silicon carbide comes with many advantages but it also requires the mastering of several technical design challenges.
