Interview Question in Zener diode

Interview Question :: Building a 400V Power Supply Circuit Help/Check

diagram: http://www.alexnwolf.com
I have used a series of zener diodes to step the theoretical 680VDC down by 400VDC to produce 400VDC across the 4 diodes.

The circuit should draw about .01A across the resistor at 680VDC.

Question: Will the voltage potential stay 400VDC across the Zener diodes with an empty capacitor bank? Full Bank? Will it even work?

RE: Building a 400V Power Supply Circuit Help/Check?
The voltage doubler rectifier circuit is wrong. Please check http://hyperphysics.phy-astr.gsu.edu/hba... You can also use voltage multiplier http://en.wikipedia.org/wiki/Voltage_mul... Yes, 400Vdc will stay with empty or full bank, and it will work as long as you change the doubler circuit. Congratulations. Good effort!! Note: make sure you leave at least one capacitor in the bank to smooth out the DC ripple. Also their rating should be at least 400V.
