How does a capacitive filter work?

A capacitive filter smooths additional pulses in the output stage so that an almost constant DC voltage is supplied to the load. The output filter charges up to the peak of the input voltage as seen across CF (the positive portion of the input). As the input voltage to the output stage descends below 0V, the capacitor discharges into the load.
