Step-up Cycloconverter:
A cycloconverter is a power electronic device that converts AC power of one frequency to AC power of another frequency. In a step-up cycloconverter, the output frequency is higher than the input frequency.
Input and Output Frequencies:
Given that the input frequency is 50 Hz and the output frequency is 100 Hz.
Half Wave Input:
When one half wave of the input voltage is considered, it means that only one positive half cycle of the sine wave is taken into account.
Output Waveform:
In a step-up cycloconverter, the output waveform consists of multiple cycles of the output frequency for each cycle of the input frequency.
Explanation:
When a single half wave of the input voltage is considered, it means that only the positive half cycle of the sine wave is taken into account. Since the input frequency is 50 Hz, one half wave corresponds to 1/100th of a second (1/2 * 1/50 = 1/100).
In a step-up cycloconverter, the output frequency is higher than the input frequency. In this case, the output frequency is 100 Hz. This means that for every second, there are 100 cycles of the output waveform.
Since the input waveform consists of only one half wave (1/100th of a second), the output waveform will consist of 100 cycles of the output frequency. Therefore, for every half wave of the input, there will be one full wave of the output.
Hence, the correct answer is option 'B' - one full wave of output.

Hence, the correct answer is option 'B' - one full wave of output.
