Comparison of Design and Simulation of Step up Converters with Inverters for Solar Application

Now a days as per the present scenario lot of power shortages are there in all over the world especially country like India. Almost the electrical power from the fossil fuels is becoming so less some of the examples of the fossil fuels which are coal, oil and gases. So most of them looking in forward for the electrical power from green or renewable based energies like solar, biomass, wind, tidal which does not cause any pollution to the environment. This paper proposes a step up converter which is interleaved with voltage multiplier module with two types of inverter for photovoltaic power system. The main attribute of the step up converter with inverter topology is the fact which generates an AC output voltage which is larger than the DC input voltage. Operations, control strategy, modulation and experimental results are included in this paper. Firstly, step up converter interleaved with voltage multiplier module with full bridge inverter is compared with step up converter with voltage multiplier module with half bridge inverter is done in Matlab/ Simulink. The FFT spectrums for the outputs of the system are compared and presented to validate the proposed control strategy. Then step up converter interleaved with voltage multiplier module with inverter is compared with conventional step up converter with inverter for solar application.
