???????

A single phase series full converter is operated from a \( 110 \mathrm{rms} \mathrm{V}, 50 \mathrm{~Hz} \) supply. The load current is constant due to the large inductance value of the load and the load resistance \( R=10 \Omega \). The turns ratio of the transformer is \( N_{p} / N_{s}=2 \). If the delay angles are \( \alpha_{1}=0 \) and \( \alpha_{2}=5 \pi / 6 \) : a- Calculate the supply power factor, the average values of load and thyristors currents and sketch the waveforms of supply voltage, output voltage and supply current. b- If \( \alpha_{1}=\pi / 6 \) and \( \alpha_{2}=2 \pi / 3 \), sketch the waveform of supply current.
