Abstract

Solar energy is widely used among the various renewable energy sources since it is conveniently accessible. Various Non-Isolated DC-DC converter configurations, such as Boost, Buck-Boost, and CUK, associated with Maximum Power Point Tracking (MPPT) controller i.e., Perturb-observation (P&O) and Incremental Conductance (INC) to bring out MPP from Solar Photovoltaic (PV) System, discussed in this article. Controlling the switching operations of the converters by providing the appropriate switching pulse to the DC-DC converter through the MPPT controller allows the desired output voltage of 220V DC to be maintained across the load. This article tries to analyze and examine the characteristics of the various converters to find out more optimum converter for different operating situations. The performance parameters, taken as output voltage, ripple in output voltage and current, output power, efficiency, and required size of passive elements are needed. The desired responses of mathematical modelling are verified through the simulation, which is executed in MATLAB/Simulink.
