actually working on a step-up converter (see file attached) at the university.
For further improvements I need a simulation of the converter. As you can see
from the paper attached I have to implement a transformer with 4 windings:
two primary and two secondary windings.
I tried to
implement the transformer coupling four inductances with the part “K_linear”.
Unfortunatelly the results didn’t really match with the measurements. For high
input voltages (20mV to 30mV) the output voltages of the converter were to
high, for low input voltages (10mV to 15mV) the transformer didn’t start up.
opinion this behaviour is strongly influenced by the core material of the transformer. Therefore I need a better model of the transformer. For the
transformer I used a EP13 core (N87 core material). Could you please
explain how a transformer with four windings
and a specific core should be implemented? Could you give me some links to good tutorials on this topic?
it is important to understand that the potential difference of a signal indicates the strength of the magnetic field formed due to that signal specifically in your case because you’ll won’t be forcing more current to flow through the windings at lower potential difference. In my opinion, you either need to increase the current of the signal or perhaps use a material with greater magnetic permittivity.
