Simulation of interleaved flyback converter with incremental conductance mppt for solar pv array using matlab/simulink

Abstract

The simulation of an interleaved flyback converter with solar system as input source is discussed in this paper. The interleaved flyback converter topology is adopted to prevent the generation of excess heat in devices, to avoid large voltage ripple in the load and also to minimise the size of the filtering elements. The control of the converter circuit is performed using Maximum Power Point Tracking (MPPT) controllers to get maximum power from the solar panel. In Maximum Power Point Tracking we used incremental conductance algorithm. This method is widely implemented because it has the higher steady-state accuracy and environmental adaptability. Simulation was performed with different duty cycle to study the output voltage variations thus the results obtained can be analysed. The design has been tested through simulation in MATLAB/SIMULINK model.
