EFFECT OF THE RIPPLE CURRENT ON POWER FACTOR OF CRM BOOST APFC
Boost Active Power Factor Corrector operating in a Borderline or Critical Conduction Mode is reexamined. Approximate analytical expressions of the inductor RMS current as well as estimation of Power Factor of the APFC are obtained. Based on the proposed theory, the paper suggests simple design criteria for the line filter.
