Paper Title
Comparative Study of Active Power Factor Correction In AC-DC Converters
Abstract
Majority of the applications involving electronic circuitry such as those used in automotive applications and
battery chargers require a regulated DC supply. Since AC supplies are more commonly available, a suitable AC-DC
converter becomes mandatory for such applications. These AC-DC converters involve a number of non-linear devices which
reduce the system power factor and introduce harmonics in the power system leading to adverse effects. Hence it is essential
to use a suitable power factor correction technique to condition the supply current. This paper presents a comparative
analysis of three such active power factor correction topologies. Simulation studies have been carried out using
MATLAB/SIMULINK.
