The graphs of the Ud, id, U1, I1 expressions of these rectifiers will be written in which intervals they are in the turn-on and turn-off areas of the diodes.

Answer 1

The diodes are in the turn-on area when the anode voltage is positive with respect to the cathode voltage, and they are in the turn-off area when the anode voltage is negative with respect to the cathode voltage.

Step-by-step explanation:

In a 2 Phase Half Wave Uncontrolled Rectifier with resistive load, the diodes are in the turn-on area when the anode voltage is positive with respect to the cathode voltage, while the diodes are in the turn-off area when the anode voltage is negative with respect to the cathode voltage.

In a 3 Phase Half Wave Uncontrolled Rectifier with resistive load, the diodes are in the turn-on area when the anode voltage is positive with respect to the cathode voltage, and they are in the turn-off area when the anode voltage is negative with respect to the cathode voltage.

The same principle applies to the rectifiers with inductive loads. The diodes are in the turn-on area when the anode voltage is positive with respect to the cathode voltage, and they are in the turn-off area when the anode voltage is negative with respect to the cathode voltage.
