Hello All, glad to be a part of this elite community, i have been following the forum threads for quite few days now, i am really interested to hear from Mr.Berkeman. here is my problem: we are facing a problem at the rectified output of our power supply, we have used a bridge rectifier to convert 18VAC to 24VDC. the board derives 18VAC and 30Vac, the latter one for battery charger part. the issue is that the ripple at the rectified output is shooting up to 1.5V as load increases. the 24VDC is fed onto a 12V linear regulator(LM350) and 15V linear regulator(KA7815). any load connected results in increase of the ripple. we tried LC And Phi filters for solving the issue, but of no use. the transformer being used can source up to 2A at each Output (18VAC and30VAC). the total load of the board may consume little over 2.5A, but this is supplied by the regulators. Please throw some light on this. P.S: Berkeman has been emphasising on power supply safety, and that has been taken care of. Thanks in advance.
