onsemi has secured a major design win with Sineng Electric, supplying its latest-generation hybrid power integrated modules (PIMs) for next-generation renewable energy platforms, including 430 kW liquid-cooled energy storage systems (ESS) and 320 kW utility-scale solar string inverters.
The hybrid PIM integrates onsemi’s FS7 insulated-gate bipolar transistor (IGBT) technology with EliteSiC silicon carbide diodes in a high-density F5BP package. This combination delivers measurable performance gains, including up to 0.1% higher efficiency, 10% lower switching losses, and up to 8% lower power dissipation compared to previous generations.
At the system level, these improvements translate into significant benefits for Sineng’s platforms. In solar inverter applications, benchmarking showed a 0.07% efficiency increase and a reduction of 225 W in power losses for a 320 kW system. For energy storage systems, the modules enable up to 0.75% improvement in round-trip efficiency, a 5% reduction in auxiliary power consumption, and higher overall power density.
The advanced module design also reduces thermal resistance and stray inductance through optimized packaging and direct bonded copper (DBC) substrates, enabling cooler operation and improved long-term reliability under high-load conditions.
From a market perspective, this design win highlights the continued relevance of hybrid IGBT + SiC module architectures in utility-scale applications, where cost-performance optimization remains critical. While full-SiC solutions are gaining traction, hybrid modules offer a balanced approach—delivering efficiency gains without significantly increasing system cost.
Strategically, this collaboration strengthens onsemi’s position in the fast-growing renewable energy and grid infrastructure markets, where demand is being driven by large-scale solar deployment, energy storage expansion, and the increasing power requirements of AI-driven data centers.
