Sineng using onsemi’s EliteSiC MOSFETs and IGBT-based power integrated modules
Power semiconductor IC supplier onsemi of Phoenix, AZ, USA says that its EliteSiC silicon carbide (SiC) MOSFETs and IGBT-based high-density power integrated modules (PIMs) will be integrated into the utility-scale solar inverter and industry-first 200kW energy storage system (ESS) of China-based Sineng Electric. The two firms worked together to develop optimized solutions that maximize the performance of solar inverters, energy storage and power conversion systems.
Sineng’s work with onsemi EliteSiC has led to the launch of a utility-scale solar string inverter, which is said to offer simplicity in design, reduced maintenance costs and lower downtime compared with a centralized inverter solution. The adoption of onsemi’s highly optimized single-stage PIM with multi-level topology in 200KW ESS enables what is claimed to be industry-leading system efficiency and lower total cost of ownership.
“onsemi supports us in solving the most challenging technical problems such as system-level design, simulations, thermal analysis and creation of sophisticated control algorithms,” says Sineng Electric’s chairman Qiang Wu. “Integrating the highly efficient EliteSiC technology enables us to develop and implement cutting-edge renewable energy solutions tailored to our customers’ needs. In combination with onsemi’s end-to-end SiC supply chain, we have the supply assurance to plan for long-term growth.”
Both firms will continue to collaborate on the development of new high-power products to enable a broader range of renewable energy solutions. As part of this, Sineng will adopt more EliteSiC products, benefitting from efficiency and scale.
“Together, we will leverage the benefits of onsemi’s high-performance products and Sineng Electric’s expertise in power electronics system design to deliver industry-leading solutions for sustainable energy applications,” says Asif Jakwani, senior VP & general manager of onsemi’s Advanced Power Division.
The two firms expect to extend their existing long-term supply agreement (LTSA), signed in late 2022, further demonstrating their commitment to collaboration and innovation.
