Sweeping input voltage and calculating efficiency automatically

Altair Forum User

Hello,

I am a new user to PSIM and am wondering if there is any way to step a DC input voltage and then automatically calculate a flyback converter's efficiency ( Eff=(Pout1 + Pout2) / Pin) ) for each stepped input voltage? It would be even better if this could be graphed ( Eff vs. DCin). Each DCin voltage requires the simulation to run until steady state is reached (~10 ms).

Thanks,

Hi Mark,

You can use a script to compute this. In order to include switching losses into your system you'll need to define the active switches as level 2 (FET and Diode).

The scripts examples are in the examples "Scripts" folder. There are several examples that should give you an idea how to do this.
