A Novel Approach towards Bridgeless Converter based SMPS for Power Quality Improvement

Pavitra S Bhusaraddi | Dr. Ashok Kusagur ^[3]

Abstract: The conventional SMPS used in computer & other similar appliances has major issues in supplied power on distorted input current, harmonic rich, poor power quality etc. To mitigate these issues, bridgeless SEPIC converter was proposed which provides stiffly regulated output dc voltage even under input/ load voltage variations. So that harmonics at the input side was reduced. Model was developed in MATLAB/ Sim power systems. The superior results demonstrated by the proposed model.
