A DC input filter reduces interference between the device and its DC power supply. That means it prevents noise coupling from the supply line into the device (increasing immunity) and vice versa (decreasing emissions). To filter both common mode and differential mode noise, a common mode choke is supplemented with line filters and capacitors.
A DC filter circuit is a device that eliminates ripples in an input signal and allows DC to pass to the output. DC filters circuits are mainly used with the rectifier outputs to obtain a stable, smooth DC voltage from a pulsating DC input.
An LC input filter has an effect on the control loop of the DC-DC converter, because the output impedance ZOutF of the input filter influences the DC/DC converter input ZInCon impedance. The input filter decreases the phase margin and thus degrades the transient response performance.
LDO, LC filter) helps attenuate the output voltage noise for any low noise application. Certain applications, such as test and measurement, are sensitive to output voltage ripple and routinely require low output voltage ripple. Designing a second stage filter starts with first understanding what noise needs to be attenuated.
However, to really reduce the level of conducted emissions to an acceptable level, an input filter is required. This application note considers both design and application of input filters for DC/DC converters. The input current flow of the DC/DC converter alternates with the switching frequency of the DC/DC converter.
To convert a 2nd-order LC filter to a 4th-order filter, you can add an LC filter circuit to the output filter of a switching converter. This modification would result in the following circuit: Modified buck converter with an output LC filter.

Next, a filter inductor, henceforth referred to as LF, and an additional filter capacitor (CF2) should be input of the DC/DC converter, to form an LC-filter. An LC filter reduces the noise from in- to output by 40 dB / decade. To reduce noise from a DC/DC converter, the LC filter should be optimized with a corner frequency

DC EMI filters are used to reduce the electromagnetic noise on electrical systems. DC EMI filters allow DC and low-frequency currents to pass through while blocking harmful high-frequency currents. This allows devices to work correctly by diverting unnecessary noise, ideal for protecting solar panels whilst reducing EMI radiation.
