step-up transformer
Definitions
Construction
Electronics
- A transformer whose
output voltage
is higher than its inputvoltage
. Asecondary winding
of such a transformer has more turns than theprimary
. Such a transformer may have multiplesecondary
windings. Used, for instance, to increase the voltage of electricity as it leaves thepower generating station
and enters the transmission system. The output voltage of a step-down transformer is lower than its input voltage. Also spelled stepup transformer.
