For a PhD project I am designing a high voltage power supply which has a maximum operating voltage of 5kVDC. The output voltage ripple is very important for the converter. The maximum allowable output voltage ripple is 200mV peak-to-peak.
I would like to know peoples thoughts on how this could be achieved. Considering the high output voltage it is undesirable to have an LC filter, my only other idea would be to use an RC filter. But to get the attenuation I need I will either need a high value capacitor (which is limited due to the HV output) or a high value resistor (which will lead to high losses in the converter).
Any other suggestions that I could look into would be appreciated.
