Comparative study of Zeta converter and Boost converter Using PI controller

The prime objective of this research is to compare the behavior of Zeta converter and Boost converter in order to achieve robust time response and proper voltage regulation in a closed-loop system. An adjustable voltage gain that depends on the duty ratio of the switch at high frequency is also observed in this article. A small-signal model for both converters is derived to achieve linearity of the system. The Ziegler-Nichols Frequency Domain Method (ZNFDM) is used for the tunning of Proportional-Integral (PI) controller to achieve better performance of the model. The time domain scrutiny of the model is performed in MATLAB/Simulink software, which depicts an improved transient response of the system.
