Following are main difference between shunt voltages regulator and series voltages regulator
| Shunt voltages regulator | Series voltages regulator |
|---|---|
| Shunt voltage regulator has good voltage regulation even at high load currents. | Series voltage regulator has not so good voltage regulation at high load currents. |
| In the shunt voltage regulator the output DC voltage is constant. | In the series voltage regulator the output DC voltages is not constant. |
| Shunt voltage regulator is connected in shunt with the load. | Series voltages regulator is connected in series with the load. |
| Shunt voltages regulator has good efficiency for low load current. | It has good efficiency for higher load currents. |
| It is appropriate for light loads. | It is appropriate for heavy loads. |
| Shunt voltage regulator has poor voltage is constant. | Series voltages regulator has better voltage regulation. |
| The control element has to bear the load voltage across it. So, it is a high voltage low current device. | The control element has to carry the load current. So, it is a high current low voltage device. |
