Static Characteristics of Thyristor or Silicon Controlled Rectifier(SCR)

Static characteristics of Thyristor or SCR(Silicon Controlled Rectifier):
Thyristor = Thyratron +Resistor

  • Three Terminal Four Layer Device.
  •  Modern Power Electronics Generation start up with the Invention of Thyristor.
  • The Exact Replica and small changes in the construction of Thyristor discovers many New Devices in Power Electronics.Hence,it can be said that the Heart of Power Electronics.
  • Thyristor can block Voltage in both Directions,but it can conduct only in one Direction.
Constructional Features of Thyristor:
