    Easy - a pulsation filter! :p

    Actually, it depends on the details, such as the application and the type of pulsations and the frequency. A low-pass filter or a notch filter could be used.

    For this, you would usually use a electrolytic capacitor. Although, you will need your diode bridge to rectify the AC. The capacitance value will depend upon the current output needed.
