The three-phase half-wave converter shown in Figure is operated from a three-phase Y-connected 220-V, 60-Hz supply and a freewheeling diode is connected across the load. The load current with an average value of $\mathrm{I}$, is continuous and the ripple content is negligible. If the delay angle alpha $=$ alpha/3, calculate (A) the displacement factor, and (B) the input power factor. The three-phase half-wave converter shown in Figure is operated from a three-phase $Y$ connected $220-\mathrm{V},60-\mathrm{Hz}$ supply and the load resistance is $\mathrm{R}=5\mathrm{ohm}$. If the average output voltage is $25\%$ of the maximum possible average output voltage, calculate (a) the delay angle. (b) the rms and average output currents, (c) the average and rms thyristor current A three-phase rectifier is supplied by a $480-\mathrm{V}\mathrm{ms}$ line-to-line $60\mathrm{Hz}$ source. The load is a $50\mathrm{ohm}$ resistor. Determine the average diode current.
