Why 2 rectifier is used in smps?

Answer:

Its not necessary that a power plant uses only two
rectifiers, it depends on the load present at the site and
the capacity of the rectifier or SMPS. Suppose the load at
the site is 120 Amps and the SMPS capacity is 2000W or the
current capacity of the recifier is 50 Amps. In that case 3
or more rectifiers is preffered. Rectifiers is used to
