Primary inductance of flyback transformer

Webthe equivalent circuit of a real transformer, mutual inductance appears in parallel with the primary windings only. The energy stored in the magnetization inductance is a function of the volt-seconds per turn applied to the primary windings and is independent of load current. 3. Various Frequencies of Interest to Magnetic Devices and Copper Loss The primary winding of the flyback transformer is driven by a switch from a DC supply (usually a transistor). When the switch is switched on, the primary inductance causes the current to build up in a ramp. An integral diode connected in series with the secondary winding prevents the formation of secondary current that would eventually oppose the primary current ramp.
