Flyback transformers are designed with all types of cores. Ferrite cores have several advantages such as ease of winding on a bobbin with integral terminal pins, better options for winding design ...

The frequency is to be 50 kHz, with a 50% ON period for Q1 (10µs). A gapped ferrite core with a pole area of 100mm 2 is to be used. The example assumes 100% efficiency and zero diode drop.

Figure 4 Transformer with trimmed RTV-11 By allowing the RTV-11 some room to expand without impinging on the ferrite, core cracking was prevented. Also, while this was indeed a high voltage ...

The shunt capacitance calculation results which are very small, and even negative, tell us that the shunt capacitance of this transformer is essentially negligible. Just as a quick check, 70.7 / 17.1 ...
