An Active Power Factor Correction Technique for Bridgeless Boost AC-DC Converter

Modified Bi-directional AC/DC Power Converter with Power Factor Correction

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

Low Cost AC/DC converter with Power Factor Correction

Simulation of Active Power Factor Correction Using Boost Type Converter

With the vast development in the usage of Power electronic devices like Rectifiers (nonlinear loads) the current drawn from the line is distorted resulting in a High Total Harmonic Distortion (THD) and Low Power Factor (PF). Hence there is a continuous need for Power factor improvement and reduction of line current harmonics. The most popular topology for Active PFC is a boost converter as it d...
