Two-Phase Interleaved Boost Converter Using Coupled Inductor …

Webthe coupled inductor structure of the 2-phase interleaved boost converter shown in Fig. 1. The inductor voltages of the coupled inductor shown in Fig. 2 are in phase, which means the maximum flux of the core is the sum of the maximum fluxes during windings 1 and 2. However, for interleaved converters, the inductor voltages are phase shifted. WebOne challenge with a CCM totem-pole PFC is that the input current has big spikes at AC zero-crossing. The issue is inherent with totem-pole PFC topology and is very complicated. Circuit characteristics that can generate these spikes include the turn-on sequence of the switches, slow reverse recovery of Q1 and Q2 body diodes, large C red faction intro
