capacitor charging switching mode supply
Hi FvM
i believe it is not possible to use a linear 2Kv post regulator in output!
you should use a step up transformer and flyback configuration to generate
2KV in output , the ripple of the output depends on the current of the output and the capacity of the output capacitor and also switching frequency , the current ripple is dependent on ESR of the output capacitor, so you should use
a high quality type capacitor as polypropylene , only the problem is its high voltage
2KV that you should series some capacitors, for the designing of the transformer you should consider enough isolation between input and output....
