Transformer Power Calculation

For a supply voltage of volts at Hz and a primary inductance = 1 Henry. Primary turns: = Secondary turns: = Secondary voltage: =volts

Assuming identical geometry, the secondary inductance

= H.

Assuming ideal coupling, mutual inductance M = H

Primary winding resistance

=

Secondary winding resistance

=

Secondary load resistance

=

With the above specified parameters, the calculated values are:

Effective primary resistance

The power dissipated in the primary winding = W = % of the power.

The power dissipated in the secondary winding = W = % of the power.

The power delivered to the load = W = % of the power.
