Design of a Boost Converter with MPPT for a PV application

by Koti Babu Rasabattula

The study of the PVsystem are growing because of large, protected, important, exhaustible and availableresource for the future energy supply. The solar output power is dependent on theintensity of the solar cell temperature and radiation of the solar cells. Though PVpower generation system implements an efficient utilization of the solar energy, butthe conversion energy of the solar cell is very low. Therefore, MPPT is employed inthe PV system to make the most of the result as an output power, regardless of thepower, temperature & irradiation circumstances & of load electrical characteristics. Inthis work, a simulation model of Incremental Conductance based MPPT controlleralong with PID controller has been developed also the step up converter is utilized tocontrol the PV power using MPPT control mechanism. The PV module is examinedby means of SIMULINK software. This proposed tracker estimates the voltages ts corresponding to a maximum power delivered by solar PV array for variableirradiance and cell temperature. The cell temperature is considered as a function ofambient air temperature, the MPP tracker has been validated by employing differenttest data sets.
