How does a pure inductor work?
This energy is actually stored in the magnetic field generated by the current flowing through the inductor. In a pure inductor, the energy is stored without loss, and is returned to the rest of the circuit when the current through the inductor is ramped down, and its associated magnetic field collapses. Consider a simple solenoid.
How is leakage inductance determined?
The leakage inductance provides energy during dead-times for charging and discharging of parasitic capacitances, ensuring soft switching for primary stage switches. Thus, in Section 3, the equation for determining the leakage inductance is obtained by considering the design constraints and circuit elements.
How does Linear Technology affect inductor energy storage?
While one inductor’s current is increasing, the other’s is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor’s volume, and therefore cost, are reduced as well. See Linear Technology’s Application Note 77 for complete details.
What is the role of leakage inductance in psfb converter?
The schematic of PSFB converter together with primary switches parasitic capacitances (CA, CB, CC, CD) is presented in Fig. 4. The leakage inductance (Lk) has an important role in the operating of the converter since the energy stored helps to achieve soft switching (ZVS) for primary switches (QA, QB, QC, QD).
Does a rear-stage full-bridge circuit realize a power-factor correction?

Why is leakage inductance important?
The leakage inductance (Lk) has an important role in the operating of the converter since the energy stored helps to achieve soft switching (ZVS) for primary switches (QA, QB, QC, QD). The soft switching reduce the commutation losses and increases the overall efficiency of the converter.
