INDUCTOR CORE FOR A POWER FACTOR IMPROVEMENT CIRCUIT CAPABLE OF REDUCING COSTS BY REDUCING THE NUMBER OF CORES IN HALF

摘要

PURPOSE: An inductor core for a power factor improvement circuit is provided to design a single core application boost inductor structure by using a linear type core of a bar type.;CONSTITUTION: A core(100) of an E shape has first to third legs(110-130). The two cores of the E shape are magnetically connected and are form into an EE coupling structure. A first inductor is wound on the first leg of 2 through a bobbin for wiring. A second inductor is wound on the second leg of 2 through the bobbin for wiring. A gap is respectively formed between the two first legs, and between the two second legs. A first power switching element and a second power switching element are alternatively switched according to an interleaved switching operation having a phase angel of 180degrees.;COPYRIGHT KIPO 2012
