WebControlled Rectifier Bridge rectifiers are of many types and the basis for the classification can be many, to name a few, type of supply, bridge circuit’s configurations, controlling capability etc. Bridge rectifiers can be broadly classified into single and three phase rectifiers based on the type of input they work on. Three-phase bridge SCR control of load. REVIEW: A Silicon-Controlled Rectifier, or SCR, is essentially a Shockley diode with an extra terminal added. This extra terminal is called the gate, and it is used to trigger the device into conduction (latch it) by the application of a small voltage. See more Shockley diodes are curious devices, but rather limited in application. Their usefulness may be expanded, however, by equipping them with another means of latching. In doing so, each becomes true amplifying devices (if … See more If an SCR’s gate is left floating (disconnected), it behaves exactly as a Shockley diode. It may be latched by breakover voltage or … See more “Normal” SCRs, lacking this internal resistor, are sometimes referred to as sensitive gate SCRs due to their ability to be triggered by the slightest positive gate signal. The test … See more A rudimentary test of SCR function, or at least terminal identification, may be performed with an ohmmeter. Because the internal connection … See more
