A filter circuit is in general a combination of inductor (L) and Capacitor (C) called an LC filter circuit. A capacitor allows A.C only and an inductor allows D.C only to pass. So a suitable L and C network can effectively filter out the A.C component from the rectified wave.

Filter Capacitor Circuit To Block DC and Pass AC. It has already been discussed that it offers low resistance compared to high-frequency signals and high resistance compared to low-frequency signals. To avoid the direct current DC, we must give priority to high-frequency signal transmission. In this case, the designed circuit acts as a high pass filter. Filter …
How do we filter out the DC component of the signal? We use a capacitor to filter out the DC signal. We do this by placing the capacitor in series. In this configuration, which is the circuit you see below, this is a capacitive high-pass filter. Low frequency, or DC, signals will be blocked.
Capacitor filters use a capacitor to improve the waveform quality coming from a rectifier circuit. The capacitor itself is frequently referred to as a smoothing capacitor. Rectifiers produce a pulsed DC output, and a smoothing capacitor can be used to store charge while the pulse is at its'' peak and generate a voltage when it falls.

In three phase to DC rectifiers, no filter capacitor is required for a pure resistive load because the voltage ripple is inherently low. However, as in your case, the typical load is a variable frequency three phase inverter –PWM or 6-step. In this case, there are reactive load elements that feed pulses of current back into the DC source. Thus a "bus capacitor" is …

The value of the filter capacitor is so choosen as to provide a low resistance path to the alternating components. For DC, the capacitor acts as an open circuit. Because of low reactance path provided by the capacitor, the alternating components are by-passed to ground. Value of Shunt Capacitor Filter

LC filters refer to circuits consisting of a combination of inductors (L) and capacitors (C) to cut or pass specific frequency bands of an electric signal. Capacitors block DC currents but pass AC more easily at higher frequencies. Conversely, inductors pass DC currents as they are, but pass AC less easily at higher frequencies.
The inductor allows DC only to pass through it and capacitor allows AC only to pass through it. Thus, a circuit formed by the combination of inductors and capacitors can effectively filter the signal according to the application.

This is because a capacitor functions as the simplest noise filter by blocking DC current while allowing noise to pass. However, since there are many types of capacitors with different properties (frequency-impedance characteristics, etc.), if they are used in the wrong way, they can actually end up increasing noise. Bypass capacitors are also called decoupling capacitors. In …
The shunt capacitor filters use the property of capacitor which blocks DC and provides low resistance to AC. Thus, AC ripples can bypass through the capacitor. If the value of capacitance of the capacitor is high, then it will offer very low impedance to AC and extremely high impedance to DC. Thus, the AC ripples in the DC output voltage gets bypassed through parallel capacitor …
