# Calculate the delay angle (alpha)

The three-phase half-wave converter in figure below is operated from a three-phase wye-connected 220V, 60 Hz supply and the load resistance is R=10 ohms. If the average output voltage is 25% of the maximum possible average output voltage, calculate the delay angle (alpha).
