Collaboration Advances High-Accuracy Virtual Design of Power Apps
onsemi and Würth Elektronik announced the integration of Würth’s passive components database into onsemi’s Self-Service PLECS Model Generator (SSPMG). This web-based platform will help engineers create application-specific, high-performance PLECS (Piecewise Linear Electrical Circuit Simulation, a software tool developed by Plexim) models of complex power electronic applications, aiding in identifying and addressing performance bottlenecks early in the development cycle.
Adding Würth Elektronik’s passive system components to SSPMG will enable the switching loss models generated to achieve higher precision than previously possible.
Legacy industry PLECS models don’t always include the wide range of component characteristics such as conduction, energy loss, and thermal impedance. SSPMG’s capabilities leverage onsemi’s physically scalable SPICE models based in physics and process variations for 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 used on any given proprietary simulation platform, or uploaded into onsemi’s Elite Power Simulator (EPS). EPS provides 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.
