The capacitor can affect the signal depending on the frequency. Therefore this property is widely used in the design of filters. An analog electronic filter such as LPF can be used to perform the function of predefined signal processing. The main function of the filter capacitor is to allow low frequency and block high frequency.
In Filter circuits it will be create ripple that will degrade the components of the circuits. The circuits may or may not function, and will end up in high repair cost, if not checked immediately. If the capacitor fully charged and by mistake two terminal of the capacitor get touch.
As we use voltage regulators these capacitor filters are kept after it so that the output that is generated gets smoothened. Hence it is proved n to be more advantageous to the half and full-wave rectifier circuit. What is Capacitor Filter?
Capacitors that connected across the load in order to filter the generated output are known as the capacitor filter. Generally, a load resistor is present in both the half and full-wave circuits in order to remove the ripples from the output DC this filter is placed along with the load.
In the simple shunt capacitor filter circuit explained previously, we have concluded that the capacitor will reduce the ripple voltage, but causes the diode current to increase. This large current may damage the diode and will further cause heating problem and decrease the efficiency of the filter.
It is always better to use a shunt capacitor (C) with series inductor (L) to form an LC Filter. In the simple shunt capacitor filter circuit explained previously, we have concluded that the capacitor will reduce the ripple voltage, but causes the diode current to increase.
