ABSTRACT: This paper reports the
converter topologies which are employed for better Power Factor Correction at
the input side. The Power Factor Correction is an important factor when
considering the Power Quality. Based on the converter topologies, the
Bridgeless converters are preferred in order to reduce the number of switching
devices, losses associated with it and improve the Power Quality further more.
This paper investigates about the Power Factor performances and conduction
losses of the Bridgeless Power Factor Corrector Converters which see through
the benefits and limitations by analyzing the Bridgeless Buck-Boost Converter,
Bridgeless SEPIC converter and Bridgeless CUK converter. The resultant voltage
is fed to the BLDC motor which is rapidly replacing the Induction motor for its
better operating characteristics. These strategies are being analyzed using the
MATLAB/Simulink software and the results are verified through the experimental
analysis. The converter choice is preferred through the performance
characteristics and Power Factor Correction at the supply. The Power Factor
obtained should be within the acceptable limits under IEC 61000-3-2 standards.
