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 low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...
I was involved with high-voltage power supplies in which transformers were wound using 3019-sized ferrite cores. Transformer structures were essentially the following: Figure 1 Pot core based ...
