Most of the reported single-stage power factor corrected (PFC) rectifiers cascade a boost-type converter with a dc-dc converter. It is found that the push-pull converter, when the duty cycles are greater than 50%, can simplify the front end of the boost-type converter to a novel single-stage converter. Coupled inductor techniques provide a method to reduce the converter size and weight and to achieve a ripple-free current. All the magnetic components including the input filter inductor and the step-down transformer are integrated into a single EI core. The proposed integrated magnetic structure has a simple core structure, a small leakage inductance, and low core losses. The prototype is built to demonstrate the theoretical prediction. © 2006 IEEE.application/pdf1592595 bytesapplication/pdfen-USIntegrated magnetics; Push-pull boost converter; Ripple-free; Single-stage[SDGs]SDG7Electric filters; Electric inductors; Electric rectifiers; Inductance; Magnetic circuits; Magnetic leakage; Integrated magnetics; Power factor corrected (PFC) rectifiers; Push pull boost converters; Electric convertersjournal article10.1109/TPEL.2006.8803532-s2.0-33947165701WOS:000240567400004http://ntur.lib.ntu.edu.tw/bitstream/246246/132887/1/05.pdf
