Abstract
Over the last several years, the Department of Defense has focused on conserving energy in order to enhance its combat capabilities. Renewable energy technologies, such as wind, solar, biomass, and others, have been explored so that the military can reduce its reliance on fossil fuels and improve its operational range. One of the components to this effort is solar photovoltaic (PV) technology. The purpose of this thesis is to demonstrate the importance of using a maximum power point tracking (MPPT) algorithm to ensure that a PV system provides the most energy possible. Moreover, two different MPPT algorithms are presented in this thesis. An interleaved boost converter controls the flow of power to a load and a 24-volt source. Also, it regulates the PV panel’s voltage and current so that the panel may operate at its maximum power point. A complete model of the solar panel, boost converter, and control algorithms was created in Simulink in order to validate the system in simulation. The control algorithms were implemented using a field-programmable gate array so that the actual system could be tested and compared against the simulation. Experimental measurements validate the model and demonstrate that the MPPT algorithms perform as expected.
