Electrical Engineering XYZ MCQs

Thyristor can be protected from over voltages by using:

  1. Heat sink
  2. Snubber circuit
  3. Voltage clamping device
  4. Fuse

Correct answer: 3. Voltage clamping device

Explanation: Voltage clamping devices are designed to quickly respond to overvoltage conditions by providing a low-impedance path for the excess voltage to bypass the protected component, in this case, the thyristor. When a surge voltage exceeds a certain threshold, these devices become conductive, effectively clamping the voltage across the thyristor to a safe level.
