such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
I think you mean silicon controlled rectifier or SCR.
These are 4 layer devices made of N and P silicon in alternate layers and are an open circuit to the passage of current until a trigger pulse is applied to it's gate terminal.
The device then acts as a normal diode until the current falls below it's holding current whereupon it reverts to the open circuit state and waits for a subsequent trigger pulse.
SCR's are used in lamp dimming circuits and are often packaged as two in inverse parallel. These are called Triacs and can fully control an AC waveform.
A: It is a diode with an extra input TERMINAL called gate. This particular diode will not conduct not until there is current present at he gate or has reached forward breakdown voltage. It is actually called and SCR. It easily find applications in phase control of AC inputs Whereby the output power can be controlled by using the gate to make it conduct at a certain angle of the incoming AC
A Basic non controlled Rectifying circuit would employ single or multiple Diodes. either in a half wave, full wave or bridged full wave configuration. In a controlled rectifier the diode(s) are replaced by Thyristor(s). The Thyristor(s) with suitable circuitry these can be gated during any point in the AC input cycle thus allowing control of the DC output of the rectifier circuit.
A rectifier is an electrical device that converts alternating current, which flows in only one direction. The process is known as rectification.
that can be purely resistive or inductive
we can control in both cycle(+ or - ) of output current.
It is a silicon-controlled rectifier, converting AC to DC for use in drawworks, mud pumps, etc.:silicon-controlled-rectifier
Because it is controlled by the gate current
A simple rectifier is a diode. It only has two terminals and will only allow electron flow in one direction only. A controlled rectifier (SCR=silicon controlled rectifier) has a third connection (gate). Which as the name suggests, is a gate that controls at which point the rectifier will work. It therefore has a level of control.There are various types and you would need the application specification, to get the best use of them.
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
For the same reason that its used in transistors and resistors...Its a semiconductor.
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
conclusion of silicon control rectifier
A switch that is controlled by other electrical components.
Fully controlled rectifier uses only SCR's Negative output voltages are obtained two quadrant control wide range control costly semi converter uses diodes and SCR's only positive output voltages are obtained one quadrant control only positive half cycles are controlled

i got no idea mate
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
An SCR (Silicon Controlled Rectifier) acts like a switch when turned on. It can also be used as a rectifier.
A controlled wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Controlled wave rectification converts both polarities of the input waveform to DC (direct current), and is more resourceful.
