Abstract
Most of the AC-DC systems include an AC DC converter for power factor correction followed by an isolated DC-DC converter. AC-DC converters will introduce harmonics to the input current waveform as it contains nonlinear elements, so a suitable control technique is required to smoothen the input current to reduce harmonics. For high power applications, Bridgeless interleaved (BLIL) AC-DC converter is a preferred choice. In this paper, a comparison of different control techniques that can be used for power factor correction is presented. The comparison is done with THD of supply current, supply distortion factor and supply power factor. Simulation of a BLIL converter is carried out in MATLAB/SIMULINK environment using various control techniques and the results are presented.
