A Novel Isolated AC to DC Power Factor Corrector Rectifier with Higher Switching Frequency

The primary aim of this research paper is to design a novel low-cost ac-dc power rectifier for improving power factor and total harmonic distortion with higher switching frequency topology using fewer switches on its secondary side. This modified topology converts ac to dc power maintaining the criteria of international power conversion standards. Due to high currents on the low-voltage side and expensive prices, conventional rectifiers have considerable conduction losses, especially when multiple active devices are used in any form either in series, parallel or in combination to attain high voltage and high power levels. The suggested methodology substitutes traditional three-level converters on the secondary side with only two switches and four diodes while retaining its core converter operation. The simulation is performed in the MATLAB2019b environment.
