This paper reviews various algorithms for the implementation of MPPT in a PV module integrated with a DC-DC converter and current mode control strategies for power converters. Also, a novel multi-loop integrated MPPT and current mode control for the Single Ended Primary Inductance Converter (SEPIC) derived from the incremental conductance MPPT technique is proposed. A simulation model is developed using MATLAB/Simulink dynamic system simulation software to verify the operation of the control system developed in the paper. This ensures the efficient operation of the PV power plant by rapid and accurate tracking the maximum power point (MPP) of the PV array. Moreover, the system is seen to offer robust voltage regulation and improved dynamic response in the face of changing environmental variables.
