Design & Analysis of 5th Order DC-DC Converter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
A new two-input DC-DC converter suitable to draw power from two different dc sources feeding a common dc-bus is presented in this paper. This is a two-switch converter belongs to fifth-order family and performs bucking operation for one dc source while it allows both bucking as well as boosting feature with the second source. The salient feature of the proposed converter is that both the sources either individually or simultaneously supply power to the downstream load at reduced ripple current. This feature is particularly attractive for photovoltaic power processing applications. A digital voltage-mode controller is designed for downstream dc-bus regulation while the current controller regulates the power from the weak input power source. A 24 V, 100 Watt converter performance is analyzed and compared with the simulation observations.
