How can we protect SCR from thermal conditions

Electrical Engineering XYZ MCQs

How can we protect SCR from thermal conditions:

  1. Using CB and fuse
  2. Using equalizing circuit
  3. Use of snubber circuit
  4. Using heat sink

Correct answer: 4. Using heat sink

Explanation: Heat sinks are specifically designed to dissipate heat generated by electronic components, including SCRs. As SCRs handle high currents, they tend to generate significant heat during operation. Heat sinks provide a path for heat to move away from the SCR and dissipate it into the surrounding environment, thus helping to maintain the SCR’s operating temperature within safe limits. Therefore, using a heat sink is the most appropriate option for protecting SCRs from thermal conditions.
