What Are Super Solid-State Solutions (S4)?

Electrical devices that have switching functionality (relays, circuit breakers, fuses, etc) usually have an electromechanical part that physically switches "on and off" between a set of contacts. This part is prone to wearing out, creating faults or over-heating.

Using Infineon components you can replace the mechanical, or moving part with MOSFET (Fet) based technology that provides improved reliability, increases life-time use all in a package with advanced control and protection methods.

When these traditional, electromechanical products are upgraded inside with Infineon technology they become Super Solid-State Solutions (S4) suitable for static switching applications.

What are the benefits of a super solid-state solution?

The benefits of transitioning to a solid-state solution is dependent on the particular product itself, but if we took an example, such as relays, the benefits of a solid-state relay vs an electromechanical relay can be found here:

  • No mechanical contact and moving parts
  • Longer electrical and mechanical life expectancy and higher reliability
  • Higher shock and vibration resistance
  • It does not bounce or generate an electrical arc
  • Typically far lower power consumption than EMRs

Power distribution going smart: solid-state circuit breakers

As the world moves towards a more sustainable future, renewable energy sources are becoming increasingly popular, despite being less predictable.

As the adoption of electric vehicles increases, so does the need for peak power to keep them charged and on the road.

To manage these challenges, we need smart power distribution down to the single sub-branches so that energy needs are always met. Join us in this training to find more about it.
