Implementation of Effective Controllers for Negative Output Super Lift Luo Converter in DC Micro Grid Application

This article presents the modeling, simulation
and design of effective controllers or dual loop controller for Negative Output Super Lift Luo Converters (NOESLLC) in
continuous conduction mode (CCM) for DC microgrid
application that are attractive owing to the inclusion of
renewable energy sources. Owing to the small output voltage of these DC sources, super lift Luo Converters is essential to fix a DC source in DC microgrid. Traditional boost converter, buck converters, SEPIC and buck-boost converters have produced less voltage transfer gain and more ripples. With the aim to overcome these crisis’s, NOESLLC is proposed for DC micro grid application. The load voltage and inductor current of the NOESLLC is regulated using effective controller loops. It consists of Proportional Integral (PI) controller acting as outer voltage loop for the load voltage regulation and P controller act as inner current loop to regulate the coil current. The dual loop controller for NOESLLC is verified by developing the MATLAB/SIMULINK model at different operating conditions
