Three-phase Half-wave rectifier

Rectification of a 3-phase supply with the help of diode is shown in figure 1 along with smoothness circuit. The three diode are connected to the three phase of star-connected secondary of a 3-phase transformer. Neutral point N of the secondary is the negative terminal for the rectified output and is earthed as shown.
