Transformer modelling

This example simulates the variation of current and voltage as it passes through a transformer.

Schematic diagram of the model:

Simulation results:

Graph of input and output voltage dependence (on primary and secondary winding respectively):

Graph of input and output current dependence (on primary and secondary winding respectively):

Conclusion:

Having analysed the current graph, it can be seen that it has dropped when passing through the transformer by exactly 10 times, from a value of 139 A to 13.9 A, which is inversely proportional to the change in the number of turns on the primary and secondary windings, 10 and 100 respectively.
