3. Analysis of electrical characteristics

3.1 Transfer functions for characteristic variables

The transformer's behavior is analyzed using the equivalent electromechanical diagram in figure 6 d. Characteristic quantities such as voltage gain G, normalized output power $P_{2}^{*}$ and efficiency η are studied as a function of supply frequency and load resistance placed on the secondary, for a fixed primary voltage level V ₁...
