Figure 7. Typical clamp circuit of flyback topology

The second one is to choose a flyback transformer with ferromagnetic core features such

that the saturation current value is higher, thus limiting the uncontrolled effect of the

saturation.

However, if the geometry of the flyback transformer cannot be changed, we suggest

optimizing the transformer by introducing a gap in the ferromagnetic core. In this way, the

saturation phenomenon is reduced since the leakage inductance is slightly increased. Due

to this increase in the leakage inductance, the electrical efficiency of the system could

satisfying the initial objective.
