Providing voltage boosting DC/DC converter with direct connection between source and load

In this paper, a DC/DC converter with high gain voltage for application in photovoltaic (PV) system is suggested. The proposed structure has the advantages of the simplicity of the structure, the use of only one controllable semiconductor switch, direct connection between the input source and the load, suitable voltage gain and optimal performance in tracking the maximum power in photovoltaic systems. One of the most important features of the proposed structure is the series placement of the output capacitor and the main source. In other words, the voltage source has a short path to feed the load compared to conventional step-up converters. Theoretical analyzes are presented to investigate the performance and design of the power circuit in the continuous conduction state. To confirm the optimal performance in the photovoltaic system, the simulation results have been evaluated in MATLAB/SIMULINK software. Also, a 100 W laboratory sample of the proposed converter was made.
