Help understanding transformers in simulink
Afficher commentaires plus anciens
Hi, I'm currently working with an H-Bridge inverter but the results that I'm getting are weird.
To summarize my problem, when i connect a transformer to the H-bridge inverter my voltage behaves in a way that I'm not expecting.

Figure 1.- output voltage of the inverter without connecting a transformer
When I connect the transformer this is what i get

Figure 2.- output voltage of the inverter connecting a transformer
And the voltage that the transformer outputs is

Figure 3.- voltage from the transformer.
This is something that intrigues me because when i run the same simulation on PSIM the results are different. Can anyone help me?, I'm trying to learn how to use simulink instead of PSIM since i read somewhere that it was more useful. Thanks in advacne

Can your provide what the paramters for the transformer are? Also, can your provide a screenshot of what you expect from Psim? Your results don't necessarily look wrong for what you have in your model.

The results appears alright. The spikes in waveform could be due to inductance of transformer windings compared to their resistance i.e. L/R ratio. P.R. NARAYANASWAMY. DR. N P R IYER.

The results appears fine.
Do not care about the spikes , it is due the inductance of the transformer.
So I believe is ok.
