Altair PSIM Pro (v2026.1)
When it comes to power electronics simulation, PSIM is one of those tools you simply can’t skip. Altair PSIM Pro Full v2026.1 is the newest update, and it hands you a faster solver along with a modern schematic view. Have you tried this powerful software yet?
PSIM takes a different approach from SPICE. For example, a DC-DC converter or three-phase inverter simulation can finish in seconds, while a similar simulation in SPICE may take longer. I also went through what 2026.1 brings, and there is plenty of new stuff in there, thermal co-simulation being one of them.
I have also used it on an EV charger design myself. And yeah, the results came out accurate enough, not a hundred percent spot on, but close.
The interface still looks a bit dated next to Plexim PLECS, honestly. Still, for running power converter simulations I would say PSIM stays the more powerful one. And for turning those PSIM results into a PCB layout, you can move over to Altium Designer.
