engineering recuitment HPCL Engineer Mock Test 2024 Power Electronics and Drives Thyristors Thyristor Protection
Snubber circuits are used with thyristors to:
1
See that SCR turns ON at a voltage much less than its forward break over voltage
2
To protect the gate circuit
3
To limit the rate of rise of voltage dv/dt.
4
To limit the rate of rise of current di/dt.
