Fast Track eDrive Efficiency Maps in PSIM
This webinar walks through an end-to-end process for generating efficiency maps in PSIM - both at the inverter level and system level - by leveraging its seamless connection with Altair Flux. We'll also cover strategies and tips for making sure all operating points are hit successfully.
The simulation files, along with the presentation, can be found at the bottom of this article.
PSIM is known for its speed and robustness in the Power Electronics space, which is crucial when running multiple e-Drive operating points to steady state. But we’re not stopping there—we have other powerful tools at our disposal. Using HyperStudy, our design space exploration and optimization tool, we can fully automate efficiency map creation explore the design space properly.
Key Benefits:
✅ Time-Saving – Generate efficiency maps quickly with minimal manual effort.
✅ No Programming Required – No need for scripting; HyperStudy automates the workflow.
✅ Streamlined Workflow – Avoid tedious setups while maintaining flexibility to add your own scripts.
✅ Advanced Post-Processing – Extract insights efficiently with improved data analysis tools.
✅ Consistent Time Investment – The process remains efficient and repeatable by multiple colleagues regardless of problem complexity.

*You need to include your own WLTP data:
*Motor losses are representative - not actual results. Ideally, inverter+motor losses should be included in the Fit Model coming from a Flux motor model in PSIM.
*Please note that regenerative barking limits should be implemented on top of this simple example.
