Semikron SKiiP Modules: Enabling Advanced Energy Storage Systems
Semikron Danfoss, formed by the 2022 merger of Semikron and Danfoss silicon power divisions, brings together over 3,500 power electronics experts to serve the rapidly growing energy storage system (ESS) market. The company’s SKiiP intelligent power modules and SEMiX platform provide the high-reliability power conversion technology essential for utility-scale and commercial energy storage applications.
SKiiP 4 SiC 2kV: The 1500VDC Solution
The SKiiP 4 SiC 2kV module represents Semikron’s latest system-level building block for 1500VDC energy storage architectures. Utilizing silicon carbide technology, this module addresses the growing demand for high-voltage energy storage systems that support grid stabilization, peak shaving, and renewable energy integration. The 2kV rating provides the voltage margin necessary for reliable 1500VDC operation while maintaining high efficiency through SiC’s superior switching characteristics.
SEMiX 3p+ Platform for ESS Applications
The SEMiX 3p+ Press-Fit series is optimized for the latest generation of high-junction-temperature, high-current chips. With half-bridge modules supporting currents up to 900A and 175 degrees Celsius operating junction temperature, the platform is well-suited for high-power energy storage converters. The modules feature soldered high-current terminals, advanced thermal materials, and support for CRRC 1700V IGBT C7 chips, providing flexibility in chip selection for different ESS power levels.
SEMITRANS 20 for High-Power Storage
The SEMITRANS 20 series represents Semikron’s newest generation of high-power industrial modules. Designed for solar, wind, energy storage systems, and drive applications, these modules simplify high-voltage inverter design with support for both two-level and three-level topologies. The excellent switching performance facilitates multi-module parallel configurations, essential for scaling energy storage power capacity.
SemiSeal Reliability Technology
Energy storage systems often operate in harsh environments where hydrogen sulfide (H2S) contamination can cause dendrite formation and short circuits. Semikron’s SemiSeal technology provides a protective layer inside the power module, preventing whisker growth and enhancing humidity robustness. This is particularly important for ESS installations in industrial environments where air quality may be compromised, ensuring long-term system reliability.
Data Center and Grid-Scale Applications
Beyond traditional grid-scale energy storage, Semikron Danfoss power modules serve data center UPS and energy storage systems. Both large and small data centers rely on these modules for UPS systems and motor drives that ensure reliable power delivery and thermal management. The modules also support Power-to-X systems and green hydrogen production, where energy storage converters play a critical role in coupling renewable energy generation with industrial processes.
