DC power supply filter

[9re9]

Hi ,

I have a 24VDC unregulated power adapeter and I am trying to build a power supply filter which can filter out the 60Hz hum. Any schematics to share? The output voltage must be 24VDC.

check out the application notes of the 7824 regulator IC

if you have 24V dc unregulated the 7824 would not work... it deserves a couple of volts more than the regulated output to work... maybe you can try with a LC filter (inductor-capacitor). the higher the frequency, the better its effect... so it will probably remove spikes from your DC, asnd reduce the 60Hz hum a bit. but the voltage loss is almost zero so you will keep the 24V output.
