Question 51
Open questionEENAT2 marksNeeds review
A single-phase, full-bridge, fully controlled thyristor rectifier feeds a load comprising a 10 Ω resistance in series with a very large inductance. The rectifier is fed from ideal 230 V, 50 Hz sinusoidal source through cables which have negligible internal resistance and a total inductance of 2.28 mH. If the thyristors are triggered at an angle
, the commutation overlap angle in degree (rounded off to 2 decimal places) is ______.Log in to check the answer
