摘要
Abstract
The Boost PFC converter in Boundary Conduction Mode （BCM） was chosen as the study subject. Through analysis of zero crossing distortion of the input current, time domain model of the input current and corresponding digital method of power factor analysis were derived. A 200 watts PFC prototype was built. Experimental results show that the relative error between the calculated value of this method and the tested value of the power analyzer is below one percentage.关键词
