uncontrolled full-wave (with diode) AC / DC rectifier and the output voltage average value Va is obtained. Same resistance single phase full wave, controlled (with thyristor) AC / DC was connected to the output of the rectifier and the average value Vb of the output voltage was obtained. Va = 1.7 Vb Find the trigger angle of thyristors.
