Output current from MOSFETS (bridge) before trafo?

I having a concern about the what kind of current that I have after the MOSFETs (in the transistor bridge) before transformer.
Before the MOSFETS I have a DC current from an AC/DC converter stage. So I am a bit confused if the current before the transformer is average, peak-to-peak or RMS value? How I can see that?

Thank you.

Eh? The current drawn from the DC source has some waveform and some amplitude. You can measure the average, peak-to-peak or RMS value with an appropriate meter.
I am not sure what you're actually trying to ask?
