Multiport DC-DC Boost Converter for Utilization in PV System with Improved Gain

Abstract

Consumption of energy is progressively rising at a regular rate. To accommodate the demand for electric supply with the exhaustion of typical resources like fossil fuels, renewable energy sources like solar power, wind farms and fuel cells are preferred. DC-DC multilevel converters with high gain appear a crucial segment of the renewable energy system. When compared with common topologies the multilevel DC – DC converter has low harmonic distortion, less stress in voltage, minimum EMI noise, and a raised efficiency. To use photovoltaic (PV) systems for standalone applications or micro grid applications, the low output voltage should be boosted to a certain level, i.e a 400V micro grid will be fed with a boost converter having 20V input voltage and gain of 20 to have 400 V at its output
