WebbThis low-pass filter blocks AC and passes DC to the R load resistor. Typical of a filter used to suppress ripple from a rectifier circuit, it actually has a resonant frequency, technically making it a band-pass filter. However, it works well anyway to pass DC and block the high-frequency harmonics generated by the AC-to-DC rectification process. Webb17 mars 2024 · Low Pass Pi Filters in Power Supplies The way in which the low pass version of a pi filter removes high frequency noise allows it to be used as a strong filter for an unregulated power supply. The low pass version can also be used as the input filter on a voltage regulator circuit.
