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.

Thanks to your answer I was able to realize my mistake. I was misinterpreting the results which means that this question was poorly made. Thanks for your answer, it helped me realize where i was confusing myself
Greetings,

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.
