PSIM- Can't obtain the expected result after recreating a DAB

Luis_Alejandr0

Hi.

I'm working on DAB research and I'm trying to recreate the model from a PhD thesis. My problem is, I can't obtain the correct waveform from the inductor current (ILF). I'm able to obtain exactly the same results of the thesis from the rest of parameters, is just that current that I'm not able to replicate, so I suspect is a problem in the way I measure it. It should be swinging from positive and negative values.

I also tried to measure from other points, but I'm not able to figure where is the mistake, so I would greatly appreciate your suggestions.

Thank you very much in advance.

Hi,

I have also observed that there is a dc component in inductor current (ILF). To avoid that, you can use dc blocking capacitors, this will give you expected results (as shown in figure).

Thank you,
