DC-DC Converter Based Photovoltaic Simulator with a Double Current Mode Controller
This paper explores the performance of a DC-DC converter based with current mode controller photovoltaic (PV) simulator which emulates the output characteristics of a real PV module. A portable PV simulator prototype of 85 W is examined in terms of its steady state IV curve matching capacity and the convergence time corresponding to step change in current source load, voltage source load, and insolation levels. The current-voltage (IV) characteristics of the PV module are implemented as a look-up-table (LUT) which determines the reference output current from measured output voltage. A Thevenin Equivalent Method approach to PV arrays analysis is also included in order to model the small-signal linearized characteristics. Extensive simulation results obtained in MATLAB are included to show that the PV simulator can work in most situations as a real PV module. Preliminary experimental results verify performance with current-source and voltage-source loads.
