WebFeb 8, 2024 · Here, the charging current plays the role of gate current to turn On the SCR even the gate signal is zero. Temperature Triggering: When the Thyristor is in forward blocking mode, most of the applied voltage collects over the junction J2, this voltage associated with some leakage current. Which increases the temperature of the junction J2. WebForward-voltage triggering occurs when the anode–cathode forward voltage is increased with the gate circuit opened. This is known as avalanche breakdown, during which junction J2 will break down. At sufficient voltages, the thyristor changes to its on state with low voltage drop and large forward current.
