A half controlled single-phase bridge converter is supplying an R-L load. The triggering angle is α. If the load current is continuous, the duration for which the freewheeling of the load takes place in a half cycle of the input voltage is Correct Answer 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.
