switching transformer

Hi

I want to make one SMPS with this specification:
V(in)=24v DC I(in)=10A (two sealed acid battery)
V(out)=2500v DC I(out,max)=20 mA

I want to calculate N1,N2,B(max),L,gap length with minimum capacitive effect and skin effect with good isolation .

please help me.

by regards.

2500V output - the voltage spikes will kill yours output diodes. Delete inductor on output of transformer - after diodes. And set it anywere befor the diodes.

Added after 2 minutes:

use the brige rectifier on the output. It's the only right way, I guess.

there is a diode that suffer 20kv on forward and switch fast and prevent spike at output because of its fast on/off time. do you suggest your circuit about this?
