Onsemi’s Hybrid Power Integrated Modules Used in Sineng Electric’s Solar and Energy Storage Solutions

Why It Matters

Higher power density and efficiency directly lower capital and operating costs for utility‑scale solar and storage, accelerating grid‑scale renewable deployment.

Key Takeaways

• 32% higher power density without larger footprint
• 0.75% round‑trip efficiency gain
• 5% lower auxiliary power consumption
• Reduced switching losses and thermal resistance
• Improved reliability for high‑load operation

Pulse Analysis

Utility‑scale renewable projects are under pressure to squeeze more kilowatts out of limited real‑estate while keeping costs in check. onsemi’s hybrid power integrated modules answer that demand by marrying silicon‑based FS7 IGBTs with silicon‑carbide EliteSiC diodes in a compact F5BP package. The combination delivers a denser power architecture that can push a 320 kW inverter to 350 kW and a 430 kW storage string to higher output without expanding the chassis, a critical advantage for developers retrofitting existing sites.

The technical edge stems from a direct‑bonded copper (DBC) substrate that slashes stray inductance and lowers thermal resistance by roughly 9.3%. This thermal efficiency, paired with an 8% reduction in power dissipation and a 10% cut in switching losses, translates into tangible system‑level benefits: a 0.75% rise in round‑trip efficiency and a 5% drop in auxiliary power draw. Those gains compound across gigawatt‑scale deployments, improving overall plant economics and extending component lifespans under high‑load conditions.

From a market perspective, the partnership positions both onsemi and Sineng as providers of future‑ready, high‑performance renewable infrastructure. By delivering higher output per square foot, developers can defer costly land acquisitions and accelerate project timelines. The improved reliability and lower operating expenses also enhance the business case for long‑term power purchase agreements, making utility‑scale solar and storage more attractive to investors and grid operators seeking stable, dispatchable clean energy.
