Santa Clara, CA and Kyoto, Japan, April 28, 2025 (GLOBE NEWSWIRE) — ROHM Semiconductor today announced that SMA Solar Technology AG, a leading global specialist in photovoltaic and storage system technology, has adopted Semikron Danfoss’ Module featuring ROHM’s latest 2kV SiC MOSFETs for its new large-scale power conversion solution “Sunny Central FLEX.” This modular platform is designed to streamline and enhance grid connections for photovoltaic installations, battery storage systems, and emerging technologies.
“ROHM’s new 2kV class SiC MOSFETs are engineered to support simple, highly efficient converter topologies for 1500V DC links,’ says Wolfram Harnack, President at ROHM Semiconductor GmbH. “They are developed to meet high reliability standards and withstand cosmic radiation, addressing the demanding conditions and extended lifetime requirements of the photovoltaic sector and beyond. Our SiC device structure, combined with integrated on-chip gate resistance, simplifies device paralleling and facilitates the design of high-power modules. Mass production has already begun,” Harnack adds.
Semikron Danfoss’ SEMITRANS® 20 was developed for high power applications and fast-switching operations, representing the next generation of power modules for large converters. SEMITRANS® 20, equipped with ROHM’s 2kV SiC MOSFETs, plays a key role in SMA’s Sunny Central FLEX platform. “Semikron Danfoss and ROHM have collaborated for over a decade, focusing primarily on the integration of silicon carbide (SiC) technology into power modules. More recently, we have teamed up to incorporate silicon IGBTs as well”, says Peter Sontheimer, Senior Vice President of Semikron Danfoss’ Industry Division.
“The new SEMITRANS® 20 provides simple and efficient solutions for 1500VDC applications,” adds Sontheimer. “These modules are ideal for solar and energy storage inverters while also benefitting emerging applications such as high-power electric truck chargers and wind converters.”
“The collaboration between SMA, Semikron Danfoss and ROHM demonstrates how the seamless integration of innovative technologies creates the foundation for future-oriented energy projects,” said Bernd Gessner, Product Manager Power Conversion Systems at SMA. “The demands placed on these solutions are higher than ever. With decades of expertise, SMA meets the highest standards for performance, reliability, durability and flexibility. The fact that Sunny Central FLEX achieves these future-ready benchmarks is also a testament to the outstanding cooperation with our partners who share the same commitment to excellence.”
