onsemi is working with Sineng Electric on inverter designs for 200KW stationary energy storage systems (ESS).

Sineng in China will integrate onsemi’s EliteSiC silicon carbide (SiC) MOSFETs and IGBT-based high-density power integrated modules (PIMs) into its utility-scale solar inverter and industry-first 200kW energy storage system (ESS). The two companies worked together to develop optimized solutions that maximize the performance of solar inverters, energy storage and power conversion systems.

Sineng has launched a utility-scale solar string inverter using the EliteSiC with conversion efficiency over 99% to simplify the design, reduce maintenance costs and lower downtimes compared to a centralized inverter solution. This uses onsemi’s optimized single-stage PIM with multi-level topology in 200KW ESS.

Both companies 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 process, Sineng will adopt more EliteSiC products, thereby benefitting from efficiency and scale.

“onsemi supports us in solving the most challenging technical problems such as system-level design, simulations, thermal analysis and creation of sophisticated control algorithms,” said Qiang Wu, chairman of Sineng Electric.

“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.”

“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,” said Asif Jakwani, senior vice president and general manager, Advanced Power Division, onsemi. “Our continuous pursuit to improve overall system efficiency plays a pivotal role in society moving towards the goal of a net-zero emissions future.”

The two companies expect to extend their existing long-term supply agreement (LTSA), signed in late 2022.;
