Half-wave uncontrolled rectifier:

  • The diode will conduct when the voltage at the anode is greater than 50V.
  • It will conduct only in the positive half as it will get reverse biased in the negative half.

The diode will conduct from (180° - θ) to θ .

θ = 30° 

Tc = (180°  - 30°) - 30° 

Tc = 120°
