Hi Jenya -with the full winding, bridge and choke input you eould right around 350vdc,
I'm not familiar with the circuit but for choke input you have a minimal inductance called L critical which is defined by 1130/R (for 60Hz line) where R=E/current. Typically a choke-input supply uses 2X L critical plus a bleeder resistor pullng about 10% of the current - the bleeder of course 'bleeds' off the cap (for safety resons) when the ac is shut down and also keeps some load on the choke-input filter to prevent it from acting like a cap-filter input upon turnon.
To experiment on Duncan's program you 'right' click upon a 'block' of the diagram - then you can add a resistance between the rectifier and input cap (for cap input)
hope you have fun!
