What's wrong with my transformer model with Ansoft Maxwell

    Hi,

    I had modeled a simple transformer with Maxwell 3D (one closed iron and 2 coils), all seems all right except the output voltage, I have only 300 mV and I must have 12V ! I join the files, if someone can help me ? A strange thing is the StrandedLoss which up to 350 kW !!! where's come from this ?

    V1=12V
    V2=300mV
    Coil1=1000 turns
    Coil2=1000 turns

    Regards


    Edit: I have increase the secondary resistor : 1000 Ohms and the voltage is good. But when I want to place a small value for resistor (5 Ohms) for example, the voltage is very low ! someone has an idea where come from the problem ?

    This is not good. Coils must touch the core, they must be placed around the core and then use Baundarise - Insulating between core and coil.
