What is Thyristor
What Is Thyristor？
Thyristor,also called silicon controlled rectifier,also known as SCR.It is a half-controlled semiconductor device.Thyristor is a four-layer semiconductor structure of PNPN. It has three poles: anode, cathode and control.It has silicon rectifier feature and can work wll under high voltage,high current conditions.
