Pi filter calculation design2/28/2024 ![]() ![]() The components of these devices can be cheap, making this configuration exceptionally cost effective. One of the most common configurations uses a bridge rectifier combined with a pi filter and voltage regulator to generate a DC voltage that is stable enough to use in electronic circuits. Pi filters are one of the most commonly used rectifier filters because they output a high quality signal but are relatively simple and inexpensive. A high ripple factor indicates that the AC component within the rectifier output signal is large. This seems obvious because a pulsed signal does not bear much resemblance to a flat DC signal, but it is also reflected in properties like a high ripple factor. In comparison, real rectifiers produce a pulsed DC output that has relatively poor characteristics. Pi filters are widely used because they do an excellent job of improving the output signal, improving both on simple L or C filters as well as on an LC filter with only one capacitor and one inductor. Note that the rectifier filter is essentially just a low pass filter in which all AC components are ideally filtered out. When the pi configuration is used as a high pass filter, the arrangement is reversed, featuring two inductors and one capacitor. When serving as a rectifier filter or low pass filter, the pi filter is made of two capacitors and one inductor.
