Hi All,
I am looking through the website here: https://www.microwaves101.com/encyclopedias/charge-storage-capacitors which goes throuugh requiredd capacitance for a certain level of droop for a given pulse width for pulsed power supply. The trouble I am having is for my -6kV output 10mA 5mS pulse, the required capacitance comes out at 10uF. This is quite high for a 12kV capacitor that I would need to buy for reinforced isolation.
I think the issue is that the equation does not take into account the ability of a switched mode power supply to increase the current supplied to the capacitor to raise its voltage and reduce the effect of the droop.
Does anyone have a better way of calculating the required amount of holdup capacitance for a power supply pulsed system, considering a minimum and maximum pulse duration/frequency?
Thanks in advance,
SIC
