An interleaved converter with maximum power point tracking

This paper, discusses a non isolated boost converter with high step up gain with an MPPT controller. The converter is meant to be used as an interface between photovoltaic panels and the utility grid. The solar panel or array without an MPPT results in wasted power and number of solar panel needed to be installed increases. Incorporation of an MPPT controller ensures that a PV module or panel is maintained and operated at the voltage that results to maximum power point at all operating temperature and irradiance. MPPT Results in the reduction of overall installation cost. The MPPT is implemented using modified incremental conductance algorithm. Thus the converter delivers maximum power at all operating points. The simulations are done using MATLAB/SIMULINK software and a 30W laboratory prototype is implemented to validate the results.
