Dynamic Performance Enhancement of Modified Sepic Converter

This paper introduced a non-isolated DC-DC boost converter with high voltage gain and low switching voltage stress for any level of input and output voltage applications. The high boost converter is designed with the concept of Single Ended Primary Inductor Converter called as modified SEPIC converter. Normal Boost and SEPIC converters were assessed and compared to the updated SEPIC converter for their efficiency. For the modified converter, a 15 V input voltage and a 170 V output voltage with 100 W output power are suitable. Moreover, for switching the converter uses lower input current and displays low voltage stress. In general, the high-gain SEPIC DC-DC converters would have a high ripple value, which would make the output voltage unstable. But in our modified SEPIC converter, the output voltage and current are steady DC values without any ripples. The study of time reaction indicates that the suggested converter settles faster than the other comparable converter at steady state voltage and current.
