Hybrid module boosts solar power

onsemi’s Si/SiC hybrid power integrated module (PIM) increases the power output of utility-scale solar string inverters and energy storage systems. Compared to previous generations, the new F5BP-packaged PIM delivers greater power density and improved efficiency within the same footprint, raising the total system power of a solar inverter from 300 kW to 350 kW.

The F5BP-PIM is a flying capacitor boost module that pairs 1000-V, 500-A Field Stop 7 IGBTs with 1200-V, 120-A SiC diodes. FS7 IGBTs reduce turn-off losses and switching losses by up to 8%, while the SiC diodes enhance switching performance and decrease voltage flicker by 15% compared to previous generations.

Featuring an optimized electrical layout and advanced Direct Bonded Copper (DBC) substrates, these modules minimize stray inductance and thermal resistance. A copper baseplate further reduces thermal resistance to the heat sink by 9.3%, ensuring effective cooling under high loads. This robust thermal management maintains efficiency and longevity, making the modules well-suited for demanding applications requiring reliable and sustained power delivery.
