This article studies on the modeling, simulation and design of dual loop controller for Positive Output Super Lift Luo Converters (POESLLC) 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 fixas a DC source in DC microgrid. Traditional boost converter, buck converters and buck-boost converters has produced less voltage transfer gain and more ripples. In order to overcome these problems, POESLLC is proposed for DC micro grid application. The load voltage and coil current of the POESLLC is regulated using dual loop controller. It consists of Proportional Integral (PI) controller act as outer voltage loop for regulation the load voltage and P controller act as inner current loop to regulate the coil current. The dual loop controller for POESLLC is verified by developing the MATLAB/SIMULINK model at different operating conditions. This kind of converters may be included in the power electronics courses to support the undergraduate scholars and postgraduate scholars to explore their knowledge in the implementation aspect.
