Solution:
  • A silicon controlled rectifier is also known as thyristor rectifier.
  • It is a four layered current controlling solid state device.
  • SCRs can conduct current in only one direction (unidirectional devices). SCRs can be triggered normally by the current which is applied to the gate terminal.
