A space for simulation related technical resources and discussions.
This tutorial video covers how to add a second y-axis for waveform analysis. We use the feature to allow us to easily analyze Zero Voltage Switching, ZVS, of a phase-shifted full-bridge converter. This feature was added in PSIM version 12. https://www.youtube.com/watch?v=tsPKpRiR-jU
This video covers the use of PSIM & InstaSPIN to determine the motor parameters of a PMSM motor. The technique is applicable to any three-phase motor. PSIM generates the '*.h' files the InstaSPIN uses. InstaSPIN is an observer algorithm from Texas Instruments. https://www.youtube.com/watch?v=Dw36PCYiWSA
This tutorial video introduces the new timing axis which allows users to quickly analyze the relative timing of waveforms. To highlight this feature the gating pulses of a 10-level MMC 3-phase inverter are used. The timing of 10 gating pulses is quickly and easily analyzed in this multi-level inverter.…
PSIM v12 features improvements to the Thermal Module to abstract away complexity from the schematic. The thermal Cauer/Foster model to get from the junction to the device case is now part of the device. Also, you do not need to place ammeters to record the individual conduction and switching losses, you simply toggle…
This video introduces the new scripting feature that was added with PSIM version 11. Scripting allows you to automate batches of simulations. PSIM's scripting tools allow you to change variables, analyze waveforms, and write programs to understand your simulations faster. https://www.youtube.com/watch?v=pwVVyRkuo50
This tutorial video uses PSIM to determine the input impedance of a buck converter which has a multi-loop control scheme consisting of an inner current loop and outer voltage loop. The method used in the video is applicable to any power converter topology. https://www.youtube.com/watch?v=i6RBcBUfuxY
The Transactional Log Parser is a tool created to process the Altair license transactional logs, recorded by the Altair License Manager, resulting in an organized CSV version of the data, making this output easily compatible with other tools to extract detailed usage information to help you understand how you take…
