Learn MoreThis works if the time constant of the capacitor and the power supply output impedance is much longer than the ripple frequency (typically 60Hz or 120Hz for a small power supply in the US). The power filter is a low-pass filter, and it works because capacitors pass AC signals but block DC signals.
