The name "silicon controlled rectifier" is General Electric's trade name for a type of thyristor. ______________________________________ SCRs are unidirectional devices (i.e. can conduct current only in one direction) as opposed to TRIACs, which are bidirectional (i.e. charge carriers can flow through them in either direction). SCRs can be triggered normally only by a positive current going into the gate as opposed to TRIACs, which can be triggered normally by either a positive or a negative current applied to its gate electrode. ____________________________________ Thyristor turn on method  triggering gate triggering dv/dt triggering temperature triggering light triggering Forward-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. In this case, J1 and J3 are already forward-biased. In order for gate triggering to occur, the thyristor should be in the forward blocking state where the applied voltage is less than the breakdown voltage, otherwise forward-voltage triggering may occur. A single small positive voltage pulse can then be applied between the gate and the cathode. This supplies a single gate current pulse that turns the thyristor onto its on state. In practice, this is the most common method used to trigger a thyristor.    • Electrical Abbreviations||Electrical ...      • Industrial Automation|| PLC👁||SCADA||...      • Coconut water 💦|| नारियल पानी पीना क्...      • #mobile charger work#Charger quality#...      • Bearing replacement ||Speed drive fau...      • गुड़ और चना खाने के ये फायदे जान ,Hea...      • Insulation class part 1 💡||Insulation...      • motor torque, motor formula, motors s...      • Doctor ||Health Tips||Hospital🏥||Happ...      • गुड़ और चना खाने के ये फायदे जान ,Hea...   Temperature triggering occurs when the width of depletion region decreases as the temperature is increased. When the SCR is near VPO a very small increase in temperature causes junction J2 to be removed which triggers the device.
