There are many aspects of a power converter or motor drive that are dependent on frequency. Open-loop & loop gain transfer functions, input impedance, output impedance, etc. PSIM has several powerful algorithms to generate these curves. PSIM injects and measures perturbations in the time domain, which is exactly how this analysis is performed on the bench. Users do not need to do complex math to convert their system into an average model.
Multi-loop control (inner current, outer voltage, etc)
Motor drives
Digital control (z-domain)
Analog control (s-domain)
Thyristor control
Multi-inverter droop control
MPPT tracking
Input impedance/output impedance
Traditional tools like SPICE force end-users to convert their topology to an average model, sometimes an impossible task, or develop a custom solution to run a glacial sweep in the time domain. With PSIM, we only need to introduce a perturbation and then select the signal we want to see its relationship to.
PSIM has several algorithms. We cover:
When each should be used
How to set them up
How to troubleshoot when things go wrong
Common mistakes
We also compare results from PSIM with RidleyWorks and SmartCtrl.
