The document describes an inductor filter circuit, which consists of an inductor and capacitor to convert an AC input signal into a desired DC output by removing AC components. It details the functioning of a series inductive filter, including its advantages such as low ripple and simplicity, as well as disadvantages like poor voltage regulation and low output voltage for high inductance values. Overall, it emphasizes the filter's effectiveness in smoothing the output of rectified signals while noting its limitations in certain applications.

ROLL NUMBER : 22911A04D8
CLASS : ECE-C
SUBJECT : EDC

2. FILTER CIRCUIT
• A filter circuit is an AC circuit that filters the input signal to desired output signal.
• A filter circuit is the one which removes the ac component present in the rectified
output and allows the dc component to reach the load.
• Rectifier circuit is a filter circuit.

3. FILTER CIRCUIT
• A filter circuit is constructed using two main components, inductor and capacitor.
• An inductor allows DC and blocks AC.
• A capacitor allows AC and blocks DC.

4. SERIES INDUCTIVE FILTER
 This type of filter is also known as choke filter.
 Series Inductive Filter can be constructed by connecting the inductor in series,
between the rectifier and the load.
 The rectified voltage when passes through this filter, the inductor blocks the ac
components that are present in the signal, in order to provide a pure dc,

5. INDUCTIVE FILTER WITH FULL WAVE
RECTIFIER
• In the positive half cycle the diode D1is forward biased. The current flows through D1and
RL.
• In the negative half cycle the diode D1 is reverse biased while diode D2 is forward bias.
The current flows through D2 and Rl.
• We get unidirectional current through RL.

6. • Due to inductor L which opposes the current , it tries to make the output smooth by
opposing the ripple content in the output.
• The ripple factor is ,

7. ADVANTAGES
 The series inductor filter reduces the ripple in the DC output of rectifier circuit.
 It has no surge current through diode.
 It has low ripple factor at heavy load currents
 It’s relatively simple and inexpensive to implement.

8. DISADVANTAGES
 It gives low output DC voltage for larger value of inductance.
 It has poor voltage regulation.
 It can be affected by the parasitic capacitance of the inductor.
 It is not suitable for low voltage power supplies.
