Design and analysis of two-phase DC/DC boost converter with PI controller

in this study, design and analysis two-phase DC/DC boost converter with Proportional-Integral (PI) controller for battery charger application has been enhanced. The DC/DC converters in the power field are electronic devices used to efficiently convert DC electrical power from one voltage level to another. The inherently nonlinear characteristic of the DC/DC converters, including one known as the boost converter, is induced by the operation of the switching devices. And also, in conventional boost converter, it’s not suitable for high power conversions, since requires large duty ratio to reach desired output voltage, which produces extremely power losses in semiconductors. since this two-phase boost converter project was developed with a PI controller using MATLAB/Simulink software. Compare open-loop analysis with closed-loop using PI for the upgrade of the learning process. And also, to evaluate the close-loop system's transient response in terms of the system's overshoot and response time by using two tuning methods, the Ziegler Nichols method and the manual method. The performance was compared between the open loop and the PI controlled counterpart with the same parameters by MATLAB/Simulink simulation. Comparing these findings, it was found that manual method tuning of the PI controller converters performs surprisingly better (settling time and overshoot reduced) than the open loop equivalents
