Stability Analysis of Multi-Input DC-DC Converters

Abstract

This analyst for the most part centers around the steadiness examination of the multi-input DC converter framework. This MI contains two sources where wind and sun oriented can connect to the system. The performance of Multi-input DC Converters designed by the boost type with different converters configurations is Multi-input Boost, Buck-Boost, Sepic, Cuk, Zeta and KY Boost DC Converter. The Performance of the above converters analyzed in the closed-loop. Among this Multi-input KY boost, DC converter behaviour is superior to other MI DC Converters. MI KY boost DC converter is the most acceptable converter in terms of stability, time-domain analysis, and ripples. By comparing this, multi-input KY boost converter consumes less rise time, fall time and overshoot in percentage. Similarly, steady-state error (ESS) shows very low compared to other converters. Bode plot of a MI converter, measured gain margin in decibel and phase margin in degrees. Bode determines transfer function and pole-zero plot used to determine the balance of the plot. Dynamic conduct is tried and check with the assistance of MATLAB reproduction.
