Following are the difference between shunt capacitor and series inductor filter:
| Parameter | Shunt Capacitor | Series Inductor |
|---|---|---|
| Place of filter | Across the load | In series with load |
| Useful in | Reducing ripple in load voltage | Reducing ripple in load current |
| Lowest ripple in load voltage at | No load or light loads | Heavy loads |
| Suitable for | Light load application | Heavy load application |
| Surge current | Very high and must be controlled | Low and need not be control |
| Ripple factor | R = 1/ 4√3 FCR | R = R/3√2 WL |
| Size of filter | Small and compact | Bulky |
