Didnt got it Geon..
today i did several tests and determined the dc impedance of my power supply using the labview i determined that under 1 amp it has got a 2,5 ohm impedance, and at 150ma is up to11 ohms... h
it includes the voltage drops of all dioes and igbt...
the impedance change with load impedance but this is a range i tested with 10-20-30-40-50 ohms resistors...
i set to 1 amp with 10 ohms and see the voltage aplied, the current, and open the circuit and measure the input voltage
than maintain it and change the resistors and make the measurements
i found that it depends more on the current output so is reasonable to make graphs for output impedance vs current consume for each different load range...
