Flyback inductance
WebThe flyback voltage couples across the mutual inductance, Lm, but not the primary leakage inductance. When switch Q1 turns off, the current in both inductances will continue to flow somewhere. Mutual inductance current will divert to the secondary and flow through the Vfbsource, with current decreasing at the rate of –Vfb/Lm. WebAll circuit values such as inductance, peak and rms currents and turns ratios must be defined before beginning the magnetics design procedure. A practical design example of a flyback transformer design using this procedure is in the paper: "150 Watt Flyback Regulator". Step 1.

Fig. 1 shows an inductor connected to a battery - a constant voltage source. The resistor represents the small residual resistance of the inductor's wire windings. When the switch is closed, the voltage from the battery is applied to the inductor, causing current from the battery's positive terminal to flow down through the inductor and resistor. The increase in current causes a back EMF (…
