I have this tricky question and I can't wrap my head around it.
There is this inductor to limit the inrush current that will be charging up a capacitor. I'm questioning the design of it, but I don't know how to calculate it.
The input voltage is 240 V AC (60 Hz), so probably the worst case is about 330 V peak when this thing is energized, and I want to treat it like a DC at that moment but I'm not good at math.
The second part is a series inductor of 1 mH and then a 22 uF capacitor that gets charged.
I know that at first the inductor will be much more limiting in the current when this thing is first energized, but at the same time the capacitor represents the highest load because it is completely discharged. Then the inductor (I imagine) will quickly lose its impedance, but at the same time the capacitor gets charged and draws less current.
The questionable thing is that this inductor is only rated for 330 mA. I can't figure out if this is more than enough or not enough. Is it pretty easy to calculate this (even an approximation will be great) or is this something that is better simulated?
I had a feeling there was something wrong with this circuit. I drew a very much simplified schematic but just for reference let me include the actual thing:
