WebApr 5, 2024 · And the third equation for the average I G gives us the input port model. So we get this circuit. And finally, we can replace the two, the ideal sources with transformers. And get an equivalent circuit for the flyback. The ideal flyback has a buck type transformer, and then it's followed by a boost tra, type transformer. WebApr 8, 2024 · The output efficiency is calculated by measuring the input/output voltage and the current, as shown in Equation 1. The output voltage is measured to be 7.2 V, and the output current is 1.4 A. By equating the values of the input and the output in the equation, the efficiency of the flyback converter is calculated to be 99.6%.
