Hi James,

    Thanks for explanation, but I am still not sure about the model in our
spice. I have asked my father to run the same test
circuit on MicroSim spice (on WIN95) and he got "right" results. Are the diode
parameters not compatible?

Anyway I will check TR today. Do You want a 6 pulse converter subckt? I have
just fired it up....
