Dyco Electronics is a manufacturer of horizontal and vertical mount,
step up and step down transformer. Dyco designs prototype transformers
for commercial & military applications, aircraft communications, and
medical & ind. J-STD-001 certified soldering instructor are available
on-site.
A transformer is a device used in an electrical circuit that changes a
voltage on the primary winding to another voltage level on the
secondary winding(s). This transformation is accomplished via a mutual
coupling effect between the primary winding and secondary winding(s),
with the magnitude of change determined by the turns ratio between the
windings. If the primary winding contains more turns than the secondary
winding, then the voltage induced in that secondary winding will be
decreased by an amount equal to the turns ratio between the primary &
secondary winding, a transformer that does this is referred to as a
step down Transformer. Whereas in a transformer that has a primary
winding with less turns than the secondary, then the voltage induced in
the secondary winding is increased by an equal amount to the turns
ratio, this device is called a Step Up Transformer.
A step down transformer is defined as a transformer having secondary
voltage that is inferior than its main voltage. This sort of
transformer "steps down" the voltage applied to it.
The secondary current in a step down transformer produces voltage
decreases across the reactive and resistive parts in the secondary side
of the step down transformer. On the opposite side, the primary current
produces voltage drops across the resistive and reactive components of
the transformer's primary side. Consequently, it is quite simple to see
the primary voltage will be less than the supply voltage, and the
output will be inferior than one or the other.
Autotransformer winding is tapped at 100V so that it functions as a
200V-to-100V step down transformer. While this is an acceptable
transformer connection, its application is rather limited because of
the absence of isolation between input and output circuits.
