Capacitor filters, also known as capacitor-input filters or simply RC filters, are electronic circuits used to filter and smooth electrical signals. They consist of a capacitor (C) and a resistor (R) connected in series or parallel. Here are some of the pros and cons of using capacitor filters: Pros:
Pros: High-Pass Filtering: Capacitor filters are effective at blocking low-frequency signals while allowing high-frequency signals to pass through. They are commonly used to eliminate ripple and provide DC voltage in power supply applications.
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. A filter circuit consists of passive circuit elements i.e., inductors, capacitors, resistors, and their combination.
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.
In the inductor filter, the ripple factor is directly proportional to the load resistance. On the other hand in a capacitor filter, it varies inversely with the load resistance. Hence if we combine the inductor filter with the capacitor the ripple factor will become almost independent of the load filter.
