[Amps] Other HV rectifier diodes

[L L bahr]

If you have a 1000 volt power supply, what should the diode stack voltage rating be?  I have heard it is good practice to make it 4 times the voltage of the operating voltage.  In other words, make the diode stack good for 4000 volts for a 1000 volt supply.  Is this correct?  Also, would there be a difference when a choke input is used VS capacitive input?
