The simplest and most commonly used method for ripple reduction is the use of a large capacitor at the rectifier output, called a reservoir capacitor or smoothing filter (see Figure 4). The capacitor stores voltage during the wave''s peak, then supplies the load with current until its voltage is smaller than the now-rising rectified voltage wave.
