Question
a) A single-phase bridge type cycloconverter has input voltage of $230\text{ V}$, $50\text{ hz}$ and load of $R = 10\text{ }\Omega$. Output frequency is one-third of input frequency. For a firing angle delay of $30^\circ$, calculate i) rms value of output voltage, ii) rms current of each converter, iii) rms current of each Thyristor and iv) input power factor.
b) Explain the principle of operation of single-phase to single-phase bridge-type Step-up Cycloconverter with suitable circuit diagrams and waveforms.
