How to limit input current of Asynchrous machine?
Hey, everyone,
I wana simulate a induction motor, as shown in the image. I chose DC voltage source(220V), Universal bridge(IGBT) to get a three-phase voltage source, and chose synchronous Machine SI Units block as induction motor. The control mode is V/F, and got ideal 1373 rpm speed, but sadly, the stator current was much larger than the rate current (0.79A), I dont konw why.
Now, I tried to limit the input current by Saturation block, but it can’t conncect to Universal bridge 🙁 .
Anyone helps? Looking forward.
