Improved Reliability for Renewable Applications

As mainstays in the modern electrical grid, power converters for wind, solar, and ESS continue to push the limits of power density and reliability. Our portfolio is expanding with packaging technology and devices that support these topics.

 Engineering Reliability for a Greener Future

Discover how Semikron Danfoss is pushing the limits of power density and reliability in renewable energy applications like wind, solar, and energy storage systems. In this interview, Emiliano Meza shares insights into our latest products and technologies — designed for the toughest renewable applications. 

Ready for High-Performance Chipsets – SEMiX 3p+

This new member of the SEMiX 3 Press-Fit family is optimized for the latest generation of high junction temperature, high-current chips. Semikron Danfoss’s new SEMiX 3p+ housing enables half-bridge modules with maximum current ratings of at least 900A and operating junction temperatures of 175°C. Welded high-current terminals ensure reliable connection while advanced materials withstand and dissipate heat.

When equipped with the new 1700V IGBT C7 from CRRC, the SEMiX 3p+ provides especially improved power density and performance for high-power wind converters.

Features

  • New SEMiX 3p+ housing
  • Increased operating temperature, Tj,op = 175°C
  • Welded power terminals
  • Extended power range up to ICnom = 900A
  • Humidity-robustness
  • New 1700V chip supplier
  • New 1200V CAL 7 diodes

Multiple Sourcing – New IGBT Source for Greater Supply Security

Multiple Sourcing – New IGBT Source for Greater Supply Security

Semikron Danfoss expands its chip portfolio with the latest generation of IGBTs from CRRC. With blocking voltages of 1200V, 1700V and 2300V, as well as features including a maximum operating junction temperature of up to 175°C and low conduction and switching losses, they are ideal for 3-level ANPC converters for wind, 2-level motor drives, and power dense 1500V converters for solar, ESS, and green hydrogen. This strategic move strengthens our multi‑sourcing approach, ensuring supply security, offering the best chip for each application, and enabling true local‑for‑local production in China through our new Nanjing facility.

SemiSeal - H2S Protection and More

SemiSeal – H2S Protection and More

Power converters are increasingly deployed in environments where sulfur-containing chemicals are present, either through specific industrial processes (fertilizers from farming) or general pollution. These chemicals (typ. H2S) can react with the metals inside power modules and cause fatal short circuits when dendrites are formed. SemiSeal provides a protective layer inside power modules to prevent dendrite formation on critical surfaces. As an added benefit, in certain products, it can also increase the humidity robustness.
