Mppt Based High Gain Boost Converter for Pv Applications

Abstract

Abstract –This method proposed uses the circuit of a solar photovoltaic energy conversion system with simple and efficient additional components like fixed DC to variable DC converter, a Maximum power point tracking system to obtain desired outputs for variable product requirements. The system acts as a replacement of the battery usually used for the storage of the DC power supply that has been obtained from the Solar PV array. This, especially helps when we only get a specific power that can be used for the later use of the stored charges. To get variable voltages for the load supply, a DC-DC converter with a maximum power point tracking system is used. When compared with the buck and boost converter, the boost converter gives a much more efficient output. However, we can choose a closed loop circuit for getting the variable DC output voltage from the fixed DC voltage source which is being obtained from the solar panel. The obtained voltage can be used without batteries which is because generally DC-DC converter stores energy periodically within and releases from a magnetic field in an inductor that is present inside it. To get a different voltage for a different purpose, for example, charging of laptops, charging of mobile, glowing a bulb, a specific voltage can make better for the particular usage.
