Hi,
I’m 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.
In my 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?
Thanks in advance!
Simon
