SCOTTSDALE, Ariz., March 31, 2026 (GLOBE NEWSWIRE) -- onsemi announced today that its hybrid power integrated modules (PIMs) will be featured in Sineng Electricโs next-generation 430 kW liquid-cooled string energy storage systems (ESS) and 320 kW utility-scale solar inverter. The design win builds upon the longstanding collaboration between onsemi and Sineng to deliver high-performance, future-ready solutions in the growing renewable energy and AI infrastructure markets.
Industry-Leading Power Module Technology
At the core of Sinengโs new platforms, onsemiโs latest-generation Field Stop (FS7) insulated-gate bipolar transistor (IGBT) and silicon carbide (SiC) hybrid PIMs in the F5BP package are engineered to boost the power output of utility-scale solar string inverters and energy storage systems (ESS). Compared to previous generations, the modules offer 32% increased power density with 0.1% higher efficiency within the same footprint to increase the total system power of a solar inverter from 320 kW to 350 kW.
Setting New Standards for Efficiency and Reliability
onsemiโs hybrid F5BP PIMs integrate the companyโs FS7 IGBT and EliteSiC diode technologies, reducing power dissipation by up to 8% and switching losses by 10% compared to previous generations. Their advanced direct bonded copper (DBC) substrate design minimizes stray inductance and lowers thermal resistance to the heat sink by 9.3%. Together, the reduction in switching losses and thermal resistance enables up to 32% higher system power at the same weight and density compared to priorโgeneration designs. The modules also feature an optimized electrical layout and an innovative baseplate design that enhance thermal management. This combination enables superior system performance and enhanced long-term reliability.
Compared to previous-generation modules, onsemiโs latest FS7โbased hybrid PIM combines lower switching losses and reduced thermal resistance, enabling the following systemโlevel improvements in Sinengโs new 430 kW string ESS:
- A 0.75% increase in round-trip efficiency (RTE), building on moduleโlevel efficiency gains demonstrated in benchmark testing
- 5% reduction in auxiliary power consumption, lowering total operating costs
- Higher power density, reducing the number of required modules and cutting component costs
- Cooler operation under high loads and improved reliability
Enabling a More Stable and Reliable Renewable Grid
โUtilityโscale operators are laserโfocused on squeezing more kilowatts from the same footprint while cutting lifecycle costs. By integrating onsemiโs F5BP package hybrid modules into our 430 kW ESS and 320 kW inverter platforms, weโre addressing two industry imperatives at once: higher power density that uplifts system ratings, and conversion efficiency gains that compound at gigawatt scale. Those incremental improvements translate into real savings for product development and a more stable, dispatchable renewable grid.โ โ Jianfeng Sun, General Manager of Research and Development, Sineng Electric
โDevelopers need solutions that fit existing layouts, simplify thermal design, and reduce energy losses. By pairing FS7 IGBTs with EliteSiC diodes in our F5BP modules, we deliver higher conversion efficiency and power density without increasing the footprint, enabling significantly higher power ratings at the same system size. This combination allows utilityโscale solar and storage sites to increase output from existing installations, while improving reliability and lowering lifetime operating costs.โ โ Sravan Vanaparthy, VP & GM of IGBT Power Division, onsemi
