Flyback loss calculation

WebHence, the energy released by the flyback transformer is 2.65 µJ. Accounting for losses, you should probably bump that up to around 3.3 µJ. Using a primary inductance of 56 µH 3.3 µJ is the amount of energy needed in each switching cycle so, if you assume DCM operation and a conservative maximum duty cycle of 75% (1.5 µs) we can say: - Webis not common, and an extra method is needed to calculate the power consumption. In this article, a mathematic method is applied to estimate the power consumption. Power …
