The Silicon Controlled Rectifier (SCR) | Thyristors ... The Silicon Controlled Rectifier (SCR) SCR Conduction. If an SCR’s gate is left floating (disconnected), it behaves exactly as a Shockley diode. It may be latched by breakover voltage or by exceeding the critical rate of voltage rise between anode and cathode, just as with the Shockley diode. Silicon controlled rectifier A silicon controlled rectifier or semiconductor controlled rectifier is a four layer solid state current controlling device. The principle of four layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey and Holonyak of Bell Laboratories in 1956. scr controller system Chudov SCR CONTROLLER SYSTEM Control and Firing Circuit The SCR controller system has two printed circuit boards: The first board is ALD03, the firing circuit board, the second one is ALR02, the regulator circuit board and both boards are connected through a ribbon cable.
