Comparison Between the Performance of Basic SEPIC Converter and Modified SEPIC Converter with PI Controller

There are multiple solutions in which line current is sinusoidal. In addition, in the recent years, a great number of circuits have been proposed with non-sinusoidal line current. In this paper, a review of the most interesting solutions for single phase and low power applications is carried out. They are classified attending to the line current waveform, energy processing, number of switches, control loops, etc. The major advantages and disadvantages are highlighted and the field of application is found. The paper presents performance analysis of modified SEPIC dc-dc converter with low input voltage and wide output voltage range.
