I am trying to build a capacitor bank for a project in order to feed an inductor with "high" voltage(500V) however I only have a dc generator rated at 100V at my disposal. Charging 5 identical capacitors in series all equipped with bleed resistors would not cut it as I would get 100/5=20V on each cap. My question is whether charging each capacitor separately with 100V and then connecting them in series would get the voltage at the two ends of the circuit at 500 Volts? I understand that the capacitance would be divided by 5. So far charging each capacitor separately while they are already connected in series gives me a total voltage of 270 volts.Any idea why that happens? Any answer will be appreciated !
You could use a Marx generator. This is a circuit that charges capacitors in parallel and then connects them in series to get a high voltage. In practice, you need to worry about the leakage current through the capacitors as that will limit how long they can store charge effectively. It may be leakage current that caused you to only get 270V in your experiment.
