part b please

(a) Draw the load voltage waveform supplied by a \( 230 \mathrm{~V}, 50 \mathrm{~Hz} \) main electricity supply via a (i) Half wave controlled rectifier (ii) Full wave controller rectifier where the SCR's are given gate signals, first after \( 8 \mathrm{~ms} \) and then at \( 10 \mathrm{~ms} \) intervals (i.e. \( 8 \mathrm{~ms}, 18 \mathrm{~ms} \), \( 28 \mathrm{~ms} \), etc.) Your waveform should include a calculation for the peak output voltage the average output voltage and the ripple voltage for each rectifier. Assume no output filter capacitors used. (10 marks) (b) If the voltage supply in the example above drops by \( 10 \% \), recalculate the new firing angle (in degrees and in \( \mathrm{ms} \) ) to keep the output voltage constant for the full wave rectifier circuit.
