Consider the following statements:1. In a full converter, direction of...
A full converter operates as a rectifier in first quadrant (both V0, I0 positive) from α = 0° to 90° and as an inverter (V0 positive but I0 negative) from α = 90° to 180° in the fourth quadrant as shown below.

Thus, statement-4 is not correct. Statements 1, 2,3 and 5 are correct.

Consider the following statements:1. In a full converter, direction of...
Correct answer:

a)1, 2, 3 and 5

Explanation:

Full converters are AC to DC converters that have the ability to change the direction of current as well as the polarity of output voltage. Semi-converters, on the other hand, can only operate in one quadrant. The given statements can be explained as follows:

1. In a full converter, direction of current cannot reverse: This statement is incorrect. The direction of current in a full converter can be reversed by changing the firing angle of the thyristors.

2. Semi-converters are single quadrant converters: This statement is correct. Semi-converters can only operate in the first or third quadrant of the voltage-current plane.

3. A full converter can operate as a two-quadrant converter: This statement is correct. Full converters can operate in the first and fourth or second and third quadrants of the voltage-current plane.

4. A full converter operates as a rectifier in first quadrant and as an inverter in the second quadrant: This statement is incorrect. A full converter can operate as a rectifier or an inverter in any quadrant depending on the direction of current flow.

5. In a full converter, direction of current cannot reverse but polarity of output voltage can be reversed: This statement is correct. The direction of current can be changed by changing the firing angle of the thyristors but the polarity of output voltage can be reversed by changing the polarity of the DC source.

Therefore, the correct statements are 1, 2, 3, and 5.
