Onsemi introduced its latest generation of silicon and silicon carbide hybrid Power Integrated Modules (PIMs), designed to boost power output in utility-scale solar string inverters and energy storage systems (ESS). Packaged in the innovative F5BP design, these new modules offer increased power density and efficiency, enabling solar inverters to deliver up to 350kW of power - an improvement from the previous 300kW. This advancement can significantly impact large-scale solar farms, potentially saving nearly two megawatts (MW) of energy per hour, which is enough to power over 700 homes annually. The new PIMs also reduce the number of modules needed, cutting component costs by more than 25%.
These PIMs are equipped with 1050V FS7 IGBTs and 1200V D3 EliteSiC diodes, delivering superior performance with reduced power dissipation. The FS7 IGBTs minimize switching losses by up to 8%, while the EliteSiC diodes enhance switching performance and reduce voltage flicker by 15%.
Additionally, the modules employ an I-type Neutral Point Clamp (INPC) for the inverter and a flying capacitor topology for the boost module. The advanced Direct Bonded Copper (DBC) substrates and optimized electrical layout further reduce stray inductance and thermal resistance, while a copper base plate enhances thermal management, ensuring the modules stay cool under heavy loads. These features make onsemi’s PIMs ideal for high-demand applications, ensuring efficient and reliable power delivery for solar and energy storage systems.
