Question

what is the necessity of using a filter in a rectifier​

Answer 1

The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output. Thus the output of the filter circuit will be a steady dc voltage.so it is necessary to use a filter

Answer 2

• in foetus there are mostly four parts.

1. L filter
2. C filter
3. LC filter
4. π filter

• comparison of ripple factor of filters is

1. L filter have very high ripple factor.
2. C filter have moderate ripple factor.
3. LC filter have low ripple factor.
4. π filter have very low ripple factor and this filter is mostly used in devices.
