Question
a) Describe the principle of operation of single-phase half-wave phase-controlled rectifier circuit using RLE load with suitable circuit diagram and waveforms.
b) A single-phase transformer, with secondary voltage of $230\text{ V}$, $50\text{ hertz}$, delivers power to load $R = 10\text{ }\Omega$ through a half-wave controlled rectifier circuit. For a firing-angle delay of $60^\circ$. Determine the following parameters:
i) the rectification efficiency
ii) form factor
iii) voltage ripple factor
iv) transformer utilization factor.
