Whole day i am trying to simulate this converter to get current for transformer windings which will be than used for simulation (core + copper losses). But i am just not able to get this working. I was trying to change settings of transient simulation according to twinbuilder built in documentation, but no results were achieved. EDIT: I though issue are diodes, but i have figure out that there is need for Mutual inductance between secondary windings in this case "M3".

Try using different solver settings. Put in series resistance across all inductors and switches (estimate wire resistance and put it in the simulation). Also you probably need to put in a real diode model instead of the default one.
