skyymanz said:Hi, thanks for the reply. so i will need a capacitor at the output of the rectifier to filter off the ripples. any ideal wat value should i use? should i need a resistor to form a RC LPF. the input to the full bridge rectifier will be a 48V 50Hz signal. Any protection circuit should i use to protect my regulator IC ?
cheers!

i am concerned for a good regulated dc signal. i have source for the regulator and its quite ok. but wat value of capacitor should i use to minimised the ripple from the output of the amplifier? a value of 1000uF good enough??
cheers!

Thunderchild said:to calculate capacitor value: 20000/(V X I). this is for a full wave rectifier. if u r using a single diode (not this case i know) then double it. naturally u can use higher values but this is the minimum.
Thunderchild said:err rectification on the formula i posted the other day. i have just come across my old note book and found it again and it is NOT 20000/(V X I) but 20000/(V/I) and do not ask why it is not 20000/V/I because i have never tried to verify it is the same but common sense tells me it is :lol
