Designing a step down autotransformer.
Step up autotransformer calculations.
Enter the transformer rating and select the appropriate unit.
Select the number of phases from the drop down menu.
The core selection is similar to the procedure in step up autotransformer.
The quantity of power input and output for the.
A step up auto transformer works on the exact same principles as a step down transformer.
It also determines the turns ratio and type of transformer.
A step down autotransformer is to be designed with specifications like primary voltage of 230 volts secondary voltage of 110 volts output volt amp of 6 and output of 6 watts.
All the same rules apply as a step down auto transformer.
Presume that the load linked to the secondary has an impedance of 10 ohms.
This video provides an explanation of how step up.
This transformer calculator helps you to quickly and easily calculate the primary and secondary full load currents of the transformer.
With a step up transformer the load voltage will be greater than the supply voltage.
Now suppose we analyze a circuit containing a step up transformer one with more turns of wire in the secondary coil than in the primary coil.
In this example i show a step up transformer with a 1 2 step ratio.
