A Study on the Design of 300W Power Factor Correction using Interleaving Method-TAE-WOO KIM DEPT. OF ELECTRICAL ENGINEERING GRADUATE SCHOOL CHANGWON NATURAL UNIVERSITY
Generally, critical conduction mode(CRM) boost PFC converter used low power level and continuous conduction mode(CCM) boost PFC converter is used in medium or high power application. Critical conduction mode boost PFC converter can be used in medium or high power application by using interleaving technical. Interleaved critical conduction mode boost PFC converter can reduce current ripple for higher system reliability and smaller buck capacitor and EMI filter size. In this paper, The design of 300W PFC preconverter using interleaving method which can improve light-load efficiency and have many advantage, is presented.
