Q1:

A single phase step up cycloconverter changes 50 Hz to 100 Hz. Then one half wave of input will give rise to

A one half wave of output

B one full wave of output

C two full waves of output

D either (b) or (c)

ANS:B - one full wave of output

Since output frequency is 2f, one half wave of input must equal one full wave of output.
