In these high power applications interleaving PFC stages can reduce inductor area and reduce output capacitor ripple current. This is made possible through the inductor ripple current cancellation that occurs with interleaving. This application note reviews the design of a 350-W two phase interleaved power factor corrected (PFC) pre-regulator.
This paper introduces the optimal design algorithm for boosting inductors of PFC converters in terms of volume and loss. Volume and loss are difficult to compare

Boost power factor corrector (PFC) is widely used in various electronic devices due to its advantages of high efficiency, simple structure, low input current ripple and low conduction loss. However, the applications of the conventional boost structure are gradually limited as the output power demand is continuously increasing this paper, an interleaved voltage
In higher power applications, to fully utilize the line, power factor correction (PFC) is a necessity. Passive solutions were developed first, which required bulky inductors and
The proposed interleaved control strategy not only retains the advantages of traditional single-phase boost converters, but also reduces the volumes of energy storage

The size of this energy is proportional to the inductance values of inductors. Power inductors, also known as power coils or power chokes, are major components used in power circuits running on a switching method in devices such as DC-DC converters, and they play the role of smoothing the high-frequency pulses created by the ON/OFF

Two integrated converters may be verified and analyzed in the established construction. A boost converter that controls the power factor in the suggested AC-DC converter is executed in the presented structure, as shown in Fig. 2, utilizing two switches in the left leg of the converter plus a boost inductor (S 1, S 2 and L B).).
In this paper, a COTVFC based on feed-forward control for a CRM totem-pole PFC converter was proposed. This control method only needs a single voltage loop,
Meanwhile, to improve the converter efficiency, the energy flow of the converter is optimized with an inductor current programming technique. Finally, the proposed electrolytic capacitor-less PFC SIMO LED driver is developed, designed, tested and compared with a single-stage SIMO design without active power decoupling.
4, if the energy storage inductor, the dc output voltage, the load, and the ac input voltage are unchanged, the on-time T on of the main switches is kept constant. It can be concluded that the unity power factor and the steady dc output voltage can be achieved as long as the constant on-time control of the main switches in the CRM is

Conceptually With VIN=400V, VOUT=360V, Fs=100KHz and a nominal 5A load you would design for a ripple current in the inductor of 10A which would be 36uH and knock it down/up a bit so use 30uH The result is reversal of current in the on switch prior to turn off so the body diode is taken out of the equation and, with inserted dead time, the
