WebJul 19, 2024 · The circuit has beeen normalized for better understanding. In the formula above, L1 is equal to Lw1 (the wiring inductance) and L2 is equal to the leakage inductance between the first secondary output and the second secondary output plus Lw2 the wiring inductance on the output of this secondary output. WebExample: Consider a flyback converter designed for the following specifications: 𝑉. 𝑖𝑛 = 5𝑉, 𝑉. 𝑜𝑢𝑡 = 10𝑉. A load resistance of 10 Ω is connected at the output, sothe load current drawn is 1 A. … WebFeb 11, 2016 · In a flyback transformer design you are storing energy in the primary then releasing it to the secondary. If you have leakage inductance, there is energy stored in the primary that doesn't get coupled to the secondary. This uncoupled energy has to be "burned off". This is where inefficiencies can be seen. imperial room new hamburg
