onsemi Powers Sineng Electric's Advanced Solar and Energy Storage Solutions

Core Insights - onsemi has secured a design win with Sineng Electric to integrate its latest hybrid power integrated modules (PIMs) into Sineng's next-generation 430 kW liquid-cooled energy storage systems (ESS) and 320 kW solar inverters, enhancing performance in renewable energy applications [3][6]. Group 1: Technology Advancements - The new PIMs utilize onsemi's FS7 insulated-gate bipolar transistor (IGBT) and EliteSiC technology, resulting in a 32% increase in power density and a 0.1% improvement in efficiency compared to previous generations [4][6]. - The modules are designed to reduce power dissipation by up to 8% and switching losses by 10%, contributing to enhanced thermal performance and reliability [5][6]. Group 2: Performance Improvements - Benchmark testing showed that onsemi's FS7-based hybrid PIM achieved a 0.07% efficiency improvement and reduced losses by 225 W in a 320 kW solar inverter configuration [1][6]. - The integration of these modules allows for a 0.75% increase in round-trip efficiency (RTE) and a 5% reduction in auxiliary power consumption, leading to lower operating costs [7]. Group 3: Industry Impact - The collaboration aims to meet the industry's demand for higher power density and efficiency, which are critical for utility-scale operators looking to maximize output while minimizing lifecycle costs [8]. - The advancements in technology enable existing installations to increase output without expanding the physical footprint, thereby improving reliability and reducing lifetime operating costs [8].
