Three Phase Rectifier WithPower Factor Correction Using SEPIC In DCM
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 10
Abstract
The improvement of power quality are required in AC-DC converters in terms of power factor correction. The PF is improved by reduction of total harmonic distortion at input of ac supply. Also high PF needed precisely regulated dc output. This paper briefly explains a three phase rectifer with high PF using singleended primary-inductance converter (SEPIC) operating in discontinuous conduction mode with the analysis and design. The high PF at the input ac mains is attained through the use of current control loop. Average current mode control is used in proposed topology. The DCM topology is implemented for attain improved power factor in an effective and simple manner. The advantages of DCM operation are turn-on of the power switches at zero-current, turn-off the output diode at zero-current and simple control circuitry
