Q17
A single phase full converter is connected to a 120 V, 60 Hz supply. It has a RL load having L=6.5 MH, R=0.50 and E = 10 V. The average output voltage Voc = 54 V. The output average current is assumed constant equal to 1. The equivalent circuit is given. If the nth harmonic component is expressed as below and the firing angle a = 60°, then the power factor would be equal to: MT I 1. KI Select one a 0.89 lagging b. 0.27 lagging c045 lagging d 0.72 lagging
