Ramp Triggering or Synchronized UJT Triggering of SCR
The ramp firing circuit is also known as a synchronized UJT triggering circuit. The below shows the ramp circuit used for triggering SCR.
Ramp and Pedestal Triggering of SCR – Circuit & Operation
Ramp and pedestal triggering is a modified version of ramp triggering. In this firing circuit, two thyristors T1 and T2 are connected in an
Two Transistor Model of SCR or Thyristor – Circuit Diagram & Analysis
Two transistor model is used to explain the principle of operation of thyristor in very simple way. Since, a thyristor is a four layered PNPN device,
V-I Characteristics of SCR or Thyristor – Modes of Operation
The V-I characteristics of SCR is a graph between the anode current and the anode-cathode voltage for different values of gate current.
