    In converting AC to DC, there's a few steps.

    One part of it goes like Rectify -> Filter -> Regulate.

    I want to know how come we need a filter since we already have a regulator to regulate our voltages. Can't we just regulate immediately after rectifying the voltage?

    Hello,

    Read the following PDF:

    You will see that after the rectification, the voltage still drops to zero.
    The filter capacitor will fill the gaps, so the regulator can do its job.
