Greetings everyone,
So, why is it, with a 440V secondary with a resistance of 31 ohms into a bridge, with just a 220U cap and the "standard" 5K load, do I get 473vdc and then if I uncheck soft start I get 584vdc.Which of these is correct?

Thanks,
Ray

584V is much nearer the real output.

To take account of the soft start, increase the simulation time to 10s, or even more, until the output remains flat.

Soft start adds about 1/2 second to the rise time. Total time to reach steady state depends capacitance and serial resistance. I don't think you'll need 10 seconds, but it won't hurt to try it, then you'll know how much you need to see the output.
