onsemi and Würth Elektronik announced the integration of Würth Elektronik’s passive components database into onsemi’s one-of-a-kind Self-Service PLECS® Model Generator (SSPMG). This intuitive web-based platform enables engineers to create custom high-accuracy, high-fidelity PLECS models of complex power electronic applications, which helps identify and fix performance bottlenecks early in the design process. With the addition of Würth Elektronik’s passive system components to SSPMG, the generated switching loss models achieve even higher precision than before.
Relying on laboratory configurations and environments, typical industry PLECS models don’t always reflect the wide range of conditions that component characteristics such as conduction, energy loss and thermal impedance display in practical implementations. In contrast, SSPMG’s capabilities are based on onsemi’s physically scalable SPICE (Simulation Program with Integrated Circuit Emphasis) models, which are rooted in semiconductor physics and the actual process variations in making the components, resulting in a more accurate representation of their behavior in the circuit.
“SSPMG empowers onsemi customers to autonomously generate system-level PLECS models that are tailored to their specific power application,” said James Victory Doctor of Philosophy, fellow, Modeling and Simulation Solutions, Power Solutions Group, onsemi. “Instead of going through long and costly fabrication-based cycles, customers develop and optimize their complete power systems virtually, enabling them to go to market faster.”
“With the seamless integration of Würth Elektronik’s database of SPICE models into onsemi’s SSPMG, design engineers can now select both the active onsemi components and the passive Würth Elektronik components for their application, generating a more accurate switching loss model,” said Dayana Cómbita, strategic partnership manager Europe, Würth Elektronik. “Together, we are paving the way to first-time-right, optimized system designs for our mutual customers.”
SSPMG loss models can be downloaded and then used on customers’ proprietary simulation platforms or uploaded into onsemi’s industry-leading Elite Power Simulator (EPS). EPS provides customers direct insights into how a circuit topology will perform across onsemi’s EliteSiC family of products, PowerTrench® T10 MOSFETs and Field Stop 7 (FS7) IGBTs and IPMs.

onsemi released the newest generation silicon and silicon carbide hybrid Power Integrated Modules (PIMs) in an F5BP package, ideally suited to boost the power output of utility-scale solar string inverters or energy storage system (ESS) applications. Compared to previous generations, the modules offer increased power density and higher efficiencies within the same footprint to increase the total system power of a solar inverter from 300kW up to 350kW.
This means a one-gigawatt (GW) capacity utility-scale solar farm using the latest generation modules can achieve an energy savings of nearly two megawatts (MW) per hour or the equivalent of powering more than 700 homes per year. Additionally, fewer modules are required to achieve the same power threshold as the previous generation, which can reduce power device component costs by more than 25%.
With solar power having achieved the lowest levelized cost of energy (LCOE), it is increasingly becoming the go-to source for renewable power generation around the world. To compensate for solar power’s variability, utility operators are also adding large-scale battery energy storage systems (BESS) to ensure a stable energy flow to the grid. To support this combination of systems, manufacturers and utilities require solutions that offer maximum efficiency and reliable power conversion. Every 0.1% of efficiency improvement can equate to a quarter of a million dollars in annual operational savings for every one gigawatt of installed capacity.
“As a variable energy source dependent on sunlight, continual advances in increasing system efficiencies, reliability and advanced storage solutions are needed to be able to maintain the stability and reliability of global grids during peak and off-peak power demand,” said Sravan Vanaparthy, vice president, Industrial Power Division, Power Solutions Group, onsemi. “A more efficient infrastructure increases adoption and assures us that, as more solar power generation is built out, less energy is wasted and pushes us forward on a path away from fossil fuels.”
The F5BP-PIMs are integrated with 1050V FS7 IGBT and the 1200V D3 EliteSiC diode to form a foundation that facilitates high voltage and high current power conversion while reducing power dissipation and increasing reliability. The FS7 IGBTs offer low turn-off losses and reduce switching losses by up to 8%, while the EliteSiC diodes provide superior switching performance and lower voltage flicker by 15% compared to previous generations.
These PIMs employ an innovative I-type Neutral Point Clamp (INPC) for the inverter module and a flying capacitor topology for the boost module. The modules also use an optimized electrical layout and advanced Direct Bonded Copper (DBC) substrates to reduce stray inductance and thermal resistance. In addition, a copper baseplate further decreases thermal resistance to the heat sink by 9.3%, ensuring the module remains cool under high operational loads. This thermal management is crucial in maintaining the efficiency and longevity of the modules, making them highly effective for demanding applications that require reliable and sustained power delivery.

The latest onsemi 7th generation 1200V QDual3 Insulated Gate Bipolar Transistor (IGBT) power modules offer increased power density and deliver up to 10% more output power than other available competing products. Based on the latest Field Stop 7 (FS7) IGBT technology, the 800-amp (A) QDual3 module delivers industry-leading efficiency to reduce system costs and simplify designs.
In a 150KW inverter, the QDual3 module will dissipate 200 watts (W) less in losses compared to the closest competition, significantly reducing heatsink size. QDual3 is engineered to work under harsh conditions and is ideal for high-power electronics converters such as central inverters in solar farms, energy storage systems (ESS), commercial agricultural vehicles (CAVs) and industrial motor drives.
Currently, two products are available depending on the applications – NXH800H120L7QDSG and SNXH800H120L7QDSG.
Increasing renewable energy adoption amplifies the need for solutions that can manage peak demand and ensure continuous power supply. Peak shaving, the practice of reducing electricity use during peak hours, is essential for maintaining electric grid stability and reducing costs. Using the QDual3 modules, manufacturers can construct a solar inverter and ESS that output more power in the same system size, enabling more efficient energy management and storage capabilities, and allowing for a smoother integration of solar power into the grid.
The modules also mitigate the intermittency of solar energy by storing excess power in an ESS, ensuring a reliable and consistent energy flow. For large systems, the modules can be paralleled to increase the output power up to a couple of MWs and compared to traditional 600 A module solutions, the 800 A QDual3 significantly reduces the module quantity, greatly simplifying design complexity and cutting system costs.
The QDual3 IGBTs module features an 800 A half-bridge configuration that integrates the latest Gen7 trench Field Stop IGBT and diode technology using onsemi’s advanced packaging techniques to reduce switching and conduction losses.
With FS7 technology, the die size is reduced by 30%, allowing more die per module, increasing the power density to enable the maximum current capacity up to 800 A or higher. With an IGBT Vce(sat) as low as 1.75V (175°C) and low Eoff, the 800 A QDual3 module dissipates 10% lower energy losses than the next-best alternative. The modules also meet the stringent standards required of an automotive application.
“Increased electrification of commercial fleets such as trucks and busses and the need of renewable energy sources demand solutions that can generate, store and distribute power more efficiently. Transferring energy from renewable sources to the grid, storage systems and to downstream loads with the lowest power losses possible is increasingly critical,” said Sravan Vanaparthy, vice president, Industrial Power Division, Power Solutions Group, onsemi. “With its industry-standard pin-out and market-leading efficiencies, QDual3 enables power electronics designers to plug and play these modules for an immediate performance boost in their systems.”
