Verified Answer
Consider the following statements:1. Fully-controlled and half control...
• Only fully controlled circuits are capable of inversion and therefore regeneration, while half-controlled circuits are not. Thus, statement-1 is not correct.
• Statement-2 is correct.
• Bridge circuits require twice as many thyristors than half-wave circuits to carry the same current. Thus, statement-3 is not correct.
• Statement-4 is correct.
• Statement-2 is correct.
• Bridge circuits require twice as many thyristors than half-wave circuits to carry the same current. Thus, statement-3 is not correct.
• Statement-4 is correct.

Consider the following statements:1. Fully-controlled and half control...
Statement 1: Fully-controlled and half-controlled circuits both are capable of regeneration.
This statement is correct. Regeneration refers to the process in which the energy stored in the inductive or reactive components of a circuit is returned back to the source. Both fully-controlled and half-controlled circuits are capable of achieving this regeneration effect.
Statement 2: The higher the pulse number, the lower is the magnitude of ripple voltage and current in the load-circuit and the a.c. supply.
This statement is incorrect. The ripple voltage and current are inversely proportional to the pulse number, which means that as the pulse number increases, the magnitude of ripple voltage and current decreases.
Statement 3: Bridge circuits and half-wave circuits both require the same number of thyristors to carry the same current.
This statement is incorrect. In bridge circuits, four thyristors are required to carry the same current, while in half-wave circuits, only two thyristors are required to carry the same current. Therefore, bridge circuits require twice the number of thyristors compared to half-wave circuits.
Statement 4: Half-wave circuits tend to be used for low-voltage, high-current use.
This statement is correct. Half-wave circuits are commonly used in applications where low voltage and high current are required. This is because half-wave circuits have a lower voltage drop compared to full-wave circuits, making them more suitable for high-current applications.
In summary, only statements 2 and 3 are incorrect.
This statement is correct. Regeneration refers to the process in which the energy stored in the inductive or reactive components of a circuit is returned back to the source. Both fully-controlled and half-controlled circuits are capable of achieving this regeneration effect.

This statement is incorrect. The ripple voltage and current are inversely proportional to the pulse number, which means that as the pulse number increases, the magnitude of ripple voltage and current decreases.

In summary, only statements 2 and 3 are incorrect.
