Design of High Efficiency Soft Switching Full Bridge DC-DC Converter Fed Solar Power Generation System

摘要

PV power generation system has witnessed drastic growth in the past two decades. It requires maximum power point tracking techniques to harvest probable output power from the panel due its non-linear nature. The DC-DC converters are used to raise the level of the obtained voltage from the panel. In this work, an isolated soft switching full bridge converter is proposed to increase the efficiency of the conversion system, and also to provide the isolation between the PV panel and load. In this study, Perturb and Observe and Incremental Conductance MPPT algorithms are implemented to harvest maximum available power from the PV panel and their performances are compared Real time data is collected from the PV module and the system is simulated using MATLAB/SIMULINK. Experimental results are used to validate the simulation output.
