Electrical Engineering XYZ MCQs
How can we protect SCR from thermal conditions:
- Using CB and fuse
- Using equalizing circuit
- Use of snubber circuit
- 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.
