Im, magnetizing current in the primary.

Ipeak,m, maximum or "peak" magnetizing current in the primary.

Up, energy stored in the flux of the magnetic field in the windings, as represented by the magnetizing current Im.

The magnetizing current Im of the transformer is Im Vprimary×t/Lp; here t (time) is a variable that starts at 0.

This magnetizing current Im will "ride upon" any reflected secondary current Is that flows into a secondary load (e.

In the case when there is little or no primary resistance and little or no switch resistance, the increase of the magnetizing current Im is a "linear ramp" defined by the formula in the first paragraph.

primary-coil resistance plus a resistor in the emitter, FET channel resistance), the Lp/R time constant causes the magnetizing current to be a rising curve with continually decreasing slope.

In either case the magnetizing current Im will come to dominate the total primary (and switch) current Ip.

In all cases, the rate of rise of the primary magnetizing current (and hence the flux), or the rate-of-rise of the flux directly in the case of saturated core material, drops to zero (or close to zero).

Now that the switch has opened at Topen, the magnetizing current in the primary is Ipeak,m Vp×Tclosed/Lp, and the energy Up is stored in this "magnetizing" field as created by Ipeak,m (energy Um 1/2×Lp×Ipeak,m2).

In the simplest case, the duration of the total cycle (Tclosed + Topen), and hence its repetition rate (the reciprocal of the cycle duration), is almost wholly dependent on the transformer's magnetizing inductance Lp, the supply voltage, and the load voltage Vz.

where H is the magnetizing field.
