The first of them has a multi turn primary winding on an external surface of an inner hollow lengthy metallic cylinder (with longitudinal cut) playing a role of the secondary winding.
During the first cycle the switch transistors Q1 and Q2 are in state ON and the current flows through the transformer primary winding delivering the energy for transformer (Fig.
This requires the primary side to be delta connected or the connection of a star point in the primary winding to allow for neutral current flow.
The ideal transformer model assumes that all flux generated by the primary winding links all the turns of every winding, including itself.
Performing the calculations, the transformer designed under the conventional methodology consists of a primary winding of 79 turns in 18 AWG and 165 turns in the secondary in 24 AWG gauge.
