Comparative Analysis and Exploration of a High Gain Input Current Shaped AC-DC Step-Up Converter with Feedback Controller
Abstract
This paper is focused on interprets the design and inspection of an input switched novel AC-DC step up converter with reduced THD and improved power factor. Conventional converter circuits are using a rectifier and multiple switches for AC DC conversion but the non-linear behavior of the rectifier distorts the input current waveform.
Switching at the output side of a rectifier using switch mode regulators usually can upgrade their power factor but it adds some high frequencies with the input current and requires a small-scale filter to eliminate those. As a substitute of using rectifier and multiple switches the proposed circuit uses direct input switching. Closed loop analysis of the proposed circuit is made to improve power factor (0.99) and to eliminate the THD. The inclusion of a feedback controller does not lessen the efficiency rather it has improved notably (99%).
Keywords: AC-DC Step-up Converter, Feedback Controller, Bridge Rectifier, SMPS, Duty Cycle, Total Harmonic Distortion.
