    The output of my power supply produces a really low dc output than it should be. Then I find out that it also emits ac output. So it is like that some of the ac should have been a dc to provide the right dc output.

    Anyway this my first project so I really know little yet about electronics. So any help would be appreciated.

    Show us a schematic of your circuit and the waveforms observed.

    From the little information you give one could assume that you forgit the smoothing capacitors after the bridge rectifier.
