Q1:

Assertion (A): A cycloconverter may be line commutated or forced commutated Reason (R): A step up cycloconverter requires forced commutation.

A Both A and R are correct and R is correct explanation of A

B Both A and R correct but R is not correct explanation of A

C A is correct but R is wrong

D A is wrong but R is correct

ANS:A - Both A and R are correct and R is correct explanation of A

Step up cycloconverter needs natural commutation and step down cycloconverter needs force commutation.

So, Answer B is right.
