September 4, 2024 /SemiMedia/ — onsemi has introduced its latest silicon and silicon carbide hybrid Power Integrated Modules (PIMs) in an F5BP package, designed to enhance power output for utility-scale solar inverters and energy storage systems (ESS). These new modules offer increased power density and efficiency, enabling solar inverters to boost from 300kW to 350kW. This upgrade could save up to two megawatts (MW) per hour for a one-gigawatt (GW) solar farm, equivalent to powering over 700 homes annually. The new modules also require fewer units to reach the same power level, potentially cutting component costs by over 25%.

As solar power achieves the lowest levelized cost of energy (LCOE), it is becoming a leading choice for renewable energy worldwide. To address solar power's variability, large-scale battery energy storage systems (BESS) are increasingly used to stabilize the energy grid. Efficient and reliable power conversion is critical for these systems, with every 0.1% improvement in efficiency potentially saving $250,000 annually per GW of installed capacity.

The F5BP-PIMs integrate 1050V FS7 IGBTs and 1200V D3 EliteSiC diodes to support high voltage and current power conversion with reduced power dissipation. FS7 IGBTs lower turn-off and switching losses by up to 8%, while EliteSiC diodes enhance switching performance and reduce voltage flicker by 15%. The modules feature an I-type Neutral Point Clamp (INPC) and flying capacitor topology for improved efficiency and reliability. Additionally, optimized electrical layouts, Direct Bonded Copper (DBC) substrates, and a copper baseplate enhance thermal management, reducing thermal resistance by 9.3% and maintaining efficiency under high loads.
