Methods to increase Efficiency of transformer...

"The ratio of output power to input power is called as efficiency of transformer"

efficiency = power output/ power input

Methods to increase efficiency of transformer:
  • Loop area
  • Insulation.
  • Resistance of primary & secondary coil
  • Flux coupling
Loop area:
Insulation:  The insulation between sheets of core should be perfect to stop eddy currents.
Resistance of primary & secondary coil:  The material of primary and secondary coils must be such that their electrical resistance is very small as may possible.
Flux coupling:  The primary and secondary coils should be wound in such a way that flux coupling between them is maximum because power transfer from primary to secondary coil takes place through flux linkages.
