Analysis of various DC-DC Converter Control Schemes Fed with Solar PV for PMDC Motor Drive

To meet the increasing demands of domestic and commercial applications, global attention is drastically shifting over to Renewable energy sources (RESs) such as solar, wind, geothermal, tidal, and others. Conventional energy sources, which rely on fossil fuels, are finite and environmentally destructive, causing global warming, hazardous products, and pollution. Solar PV-based power generation plays a dominant role in RESs, as it is easily accessible and requires less maintenance. Since Solar PV has limitations due to atmospheric conditions such as insolation and temperature. As a consequence, to overcome the non-linearity restriction of solar PV, MPPT controllers are extensively used to enhance the maximum power output. The MPPT controller delivers the relevant switch pulse to the dc-dc converter to obtain the maximum power and regulated output across the DC link. In this configuration, the passive elements and dc-dc converters are designed using mathematical modeling based on the switching mode operation of switches. Different controllers, PI, PO, INC & PSO, are implemented to examine the performance of PMDC motors with dc-dc converters. The mathematical modeling of each configuration is examined and simulated in Matlab/Simulink.
