A friend of mine brought a little device he made its a bridge rectifier fed straight off the mains then fed into a 900 uF capacitor the purpose of this little device is to try to make a CFL stay on for 10 seconds I don't know why it's his project. We tried this device out and after a few switch ons it popped a 5 amp fuse in the feed to my test bench so the question is what would be the charge current for a 900 uF capacitor? It made the ammeter in the feed to the test board kick up. So is there a way to work it out?
Thanks so the current is very high it's surprising just how much is involved. I know that some larger SMPS have a thermistor so when I se him again il suggest adding one. CFLs are happy with a DC or AC Iinput since the supply is rectified to DC at the input before its turned into high frequency As I say it's my mates project
