circuit with transformers

[franticEB]

Hi,
i have this circuit and i want to analyze it in theoretical way(i.e. voltage and currents involved).



could you help me?
Why D1 and D2 always conducts?
Thanks.

For a realistic analysis, at least transformer wiring resistance and diode parameters should be considered. The input current is quite high, so a saturable core might be required to represent the real behavior. Transformer leakage inductance should be considered, too.

Consider a rm8 n_87 core for T1 with wiring resistance of 40 mOhm and mur120 for the diodes d1,d2,d3.

They don't.
