Question

Difference betweeen ordinary rectifier and control rectifier

Answer 1

The triggering circuit is not required in ordinary rectifierThe triggering circuit is required in controlled rectifier.Only diodes are used in ordinary rectifier.The SCR and diodes are used in controlled rectifier.The continuous control of the output is not obtained.The continuous control of the output is obtained.The freewheeling diode is not necessary in ordinary rectifier.The freewheeling diode is necessary in controlled rectifier.The direction of power flow is form source to load only.The direction of power flow is from source to load and sometimes vice versa.Wastage of power in ordinary rectifier.No wastage of power in controlled rectifier.It is used in power supplies.It is used for speed control of DC motors.
