Option 4 : α

Circuit and waveform for half controlled single-phase bridge converter supplying an R-L load are shown below.

The waveform of freewheeling diode current shows that the current only flows for the period of α angle.
Therefore, the freewheeling of the load takes place only for α duration of angle.
