Power Factor Correction Using Sensorless Brushless DC Motor with Bridgeless Converter Topology

Abstract

In this paper the regulation of brushless drives is attained by developing a new technique called hysteretic comparator with desirable standard of power at supply mains. By this methodology the composite difference of output due to noises or undulation are avoided and the phase delay is recompensed. Fuzzy logic improves the robustness with enhancement in the consistent performance of the system. The proposed regulator operates in intermittent conduction mode which helps the accomplishment of power factor nearer unity at supply ends. Moreover absence of DBR framework offer minimized switching losses. The proposed system is developed using MATLAB 2013 and with an experiment model. Thus the harmonics are minimized and the compatible limits of various international standards like IEC 61000-3-2 and IEEE-519 standards are attained.
