M-2 type connection requires SCRs with higher PIV as compared to those in a B-2 type.
Explanation:
M-2 Type Connection:
M-2 type connection is a three-phase full-wave controlled rectifier configuration where two SCRs are connected in parallel for each phase. This configuration is commonly used in high-power applications. In M-2 type connection, the SCRs are connected in a manner that allows the current to flow through both SCRs simultaneously during each half-cycle.
B-2 Type Connection:
B-2 type connection is also a three-phase full-wave controlled rectifier configuration where two SCRs are connected in series for each phase. This configuration is commonly used in low-power applications. In B-2 type connection, the SCRs are connected in a manner that allows the current to flow through one SCR during the positive half-cycle and through the other SCR during the negative half-cycle.
PIV (Peak Inverse Voltage):
PIV is the maximum voltage that an SCR can withstand when it is reverse biased. It is an important parameter to consider while selecting SCRs for a rectifier circuit.
Explanation of the Correct Statement:
The correct statement is option 'A' - M-2 type connection requires SCRs with higher PIV as compared to those in a B-2 type.
Reason:
In M-2 type connection, the SCRs are connected in parallel for each phase. This means that during each half-cycle, the SCRs in parallel share the voltage across them. As a result, the PIV across each SCR in parallel is lower compared to the PIV across each SCR in series in a B-2 type connection.
On the other hand, in B-2 type connection, the SCRs are connected in series for each phase. This means that during each half-cycle, the entire voltage is applied across each SCR in series. As a result, the PIV across each SCR in series is higher compared to the PIV across each SCR in parallel in an M-2 type connection.
Therefore, to withstand the higher voltage in a B-2 type connection, SCRs with higher PIV ratings are required. Hence, the correct statement is that M-2 type connection requires SCRs with higher PIV as compared to those in a B-2 type.
