hi

can someone help on voltage bucking configuration/connection? wat does
it mean?

If a transformer has several windings and they are connected in series they
will either add or substract from the total voltage. That is called series
aiding or series bucking.

Simple "buck" circuit analogy:

+12V- -1.5V+
+---Batt---+---Batt---+

The 1.5 volt battery "bucks" the 12 volt battery, resulting

For completeness, here's a "boost" circuit:

+12V- +1.5V-
+---Batt---+---Batt---+
| |

The 1.5 volt battery "boosts" the 12 volt battery, resulting

The terms "buck" and "boost" are most often associated with
DC to DC converters.

In the real world circuits the "bucking" or "boosting" is not
done with batteries. Generally speaking, a voltage is created
in a coil, and the coil is electronically switched so that the
voltage in it either adds to ("boosts") the input voltage or
opposes ("bucks") the input voltage.
