High Gain Module Integrated Converter Combating Partial Shading on PV Panel

Modular, environment-friendly, low maintenance and cost effective converter fed off-grid power solution utilizing PV and battery for Telecom power supply is a requisite. This paper proposes a module integrated converter system which does the MPPT and also boosts the voltage upto usable value under various conditions of insolation variation and partial shading conditions. The current control scheme evacuates the maximum power during PV generation amidst intermittent conditions presents a slave source to a battery fed nanogrid. The performance of the system is evaluated under Matlab/Simulink environment. Presented simulation results show close conformity with design and validates the effectiveness of the system proposed.
