Following are the difference between shunt capacitor (C), series inductor (L), chokes input (LC) and π filters :
| Shunt capacitor (C) filters | Series inductor (L) filter | Choke input (LC) filter | Capacitor input (π type) filter |
|---|---|---|---|
| Only capacitor is used. | Only inductor is used. | One inductor and one capacitor are used. | Two inductors and two capacitors are used. |
| The load regulation is poor. | The load regulation is moderate. | The load regulation is good. | The load regulation is very good. |
| The ripple factor is low. | The ripple factor is high. | The ripple factor is lower. | The ripple factor is lowest. |
| The ripple reduction occurs in load voltage. | The ripple reduction occurs in load current. | The ripple reduction occurs in load current. | The ripple reduction occurs in load voltage. |
| It is suitable for light loads. | It is suitable for heavy loads. | It is suitable for light as well as heavy loads. | It is suitable for light loads. |
| The place of filter is across the load. | The place of filter is in series with the load. | The place of filter is across the load. | The place of filter is across the load. |
| It is used in cell charger, small eliminators etc. | It is used in high current DC supply. | It is used in DC power supplies. | It is used in DC power supplies. |
