SCOTTSDALE, Ariz. – March 31, 2026 – onsemi announced today that its hybrid Power Integrated Modules (PIMs) have been selected for Sineng Electric’s next-generation 430 kW liquid-cooled string energy storage system (ESS) and 320 kW utility-scale solar inverter. This design win further advances the long-standing collaboration between onsemi and Sineng in providing high-performance, future-proof solutions for the growing renewable energy and AI infrastructure markets.
Industry-Leading Power Module Technology
At the core of Sineng Electric’s new platforms are onsemi’s latest generation Field Stop (FS7) Insulated Gate Bipolar Transistor (IGBT) and Silicon Carbide (SiC) hybrid Power Integrated Modules (PIMs) in the F5BP package. These modules are designed to increase the output of utility-scale solar string inverters and energy storage systems (ESS).
Compared to previous generations, they achieve a 32% increase in power density and a 0.1% improvement in efficiency within the same footprint, enabling the total system output of the solar inverter to be increased from 320 kW to 350 kW.
Setting New Standards for Efficiency and Reliability
onsemi’s hybrid F5BP PIMs integrate FS7 IGBT and EliteSiC diode technology, delivering up to 8% lower power loss and 10% lower switching loss compared to previous generations. Additionally, the advanced Direct Bonded Copper (DBC) substrate design minimizes stray capacitance and reduces thermal resistance to the heatsink by 9.3%. The combination of reduced switching losses and thermal resistance enables up to 32% higher system output at the same weight and density as previous-generation designs. Furthermore, the optimized electrical layout and innovative baseplate design improve thermal management performance. The combination of these features results in superior system performance and long-term reliability.
When compared to previous-generation modules, onsemi’s latest FS7-based hybrid PIM enables the following system-level improvements in Sineng’s new 430 kW string ESS due to reduced switching losses and improved thermal resistance:
- 0.75% improvement in round-trip efficiency (RTE), based on module-level efficiency gains demonstrated in benchmark tests.
- 5% reduction in auxiliary power consumption, lowering total operating costs.
- Reduced number of modules required due to higher power density, lowering component costs.
- Improved reliability through cooler operation even under high loads.
Realizing a More Stable and Reliable Renewable Energy Grid
Jianfeng Sun, General Manager of the R&D Department at Sineng Electric, stated: "Utility-scale operators are focused on extracting more power from the same footprint while reducing lifecycle costs. By integrating onsemi’s F5BP package hybrid modules into our 430 kW ESS and 320 kW inverter platforms, we can simultaneously address the two critical challenges of increasing system ratings through higher power density and improving conversion efficiency. These cumulative efforts lead to the realization of a more stable renewable energy grid."
Sravan Vanaparthy, Vice President and General Manager of the IGBT Power Division at onsemi, added: "Many developers are looking for solutions that fit existing layouts, simplify thermal design, and reduce energy losses. By combining FS7 IGBT and EliteSiC diode technology in our F5BP modules, we can achieve higher conversion efficiency and power density without expanding the footprint. This enables increased output within the same system size, offering significant value in terms of both reliability and lifetime operating costs."
