Comparative Study between Conventional Booster and High Step up DC-DC Converter for Low Power PV

Abstract

Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–dc boost converter. The converter is simulated with low dc voltage input for low power applications. A 15V input voltage, 200V output voltage, and 100W output power prototype circuit of the proposed converter has been implemented. The PV model implemented with MPPT algorithm using Perturb and Observe method is used with the boost converter to get the PV module. The PV module with booster developed will give a voltage gain range of 10-12 times the input voltage. The Comparative study between the normal booster PV model and high gain PV model is done. The simulation results are presented in this paper to verify the theoretical analysis by using software MATLAB.
