Thus the ripple components will be eliminated. In other words, the inductor offers high impedance to the ripples and no impedance to the desired dc components. The inductor carries the property of opposing the change in current that flows through it.

Series Inductor FilterĪs the name of the filter circuit suggests, the Inductor L is connected in series between the rectifier circuit and the load.

The circuit diagram of a full wave rectifier with a series inductor filter is given below. All the combinations and their working are explained in detail below. Capacitor is used so as to block the dc and allows ac to pass. Inductor is used for its property that it allows only dc components to pass and blocks ac signals. The filter circuit can be constructed by the combination of components like capacitors, resistors, and inductors. Thus the output of the filter circuit will be a steady dc voltage. 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 rectifier has to be passed though a filter circuit to filter the ac components. If the rectifier output is smoothened and steady and then passed on as the supply voltage, then the overall operation of the circuit becomes better. For most applications the supply from a rectifier will make the operation of the circuit poor. For most supply purposes constant dc voltage is required than the pulsating output of the rectifier. Such supply is not useful for driving complex electronic circuits. The ripples will be minimum for 3-phase rectifier circuits. These ripples will be the highest for a single-phase half wave rectifier and will reduce further for a single-phase full wave rectifier. Apart from the dc component, this pulsating dc voltage will have unwanted ac components like the components of its supply frequency along with its harmonics (together called ripples). We have learnt in rectifier circuits about converting a sinusoidal ac voltage into its corresponding pulsating dc.
