Question

A single phase full wave mid-point SCR converter, uses
a 230/200 V transformer with the centre tap on the
secondary side. The P.I.V, per SCR is

a. 100 V
b. 1411
c. 214V
d. 282V​

Answer 1

Given:

A single phase full wave mid-point SCR converter, uses  a 230/200 V transformer with the centre tap on the  secondary side.

To find:

The P.I.V, per SCR is

Solution:

From given, we have,

A single phase full wave mid-point SCR converter, uses  a 230/200 V transformer with the centre tap on the  secondary side.

Vm = √2 Vs

Substitute the given values in the above equation.

Vm = √2 × 200

continue the further calculation.

Vm = 282.84 V

This value of the voltage can be rounded off to the nearest digit as follows.

Vm = 282

Therefore, the option (d) 282 V is correct.
