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.

What is the difference between controlled and uncontrolled rectifier?

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.

Difference between silicon-controlled rectifier and diode?

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


When an SCR turns on it acts like n?

An SCR (Silicon Controlled Rectifier) acts like a switch when turned on. It can also be used as a rectifier.


Why silicon controlled rectifier doesn't work in reverse biased condition?

Because when reverse biased it behaves like any other rectifier/diode.
