"This thesis presents a microcontroller- and DC-DC converter-based photovoltaic (PV) simulator which emulates the output characteristic of a PV module. The current-voltage (IV) characteristic of a PV module is implemented as a look-up-table that generates an output reference current based on a measured output voltage. The control mechanism is based on a double current mode controller that consists of a predictive current mode controller and a proportional-integral (PI) controller arranged in an inner loop and outer loop configuration. The PI controller is designed based on classical phase margin and gain margin criteria to ensure system stability. The performance of the portable PV simulator prototype of 85 W is examined in terms of its steady state IV curve matching capability and the convergence time corresponding to step changes in load and insolation levels. The result shows a well behaved and responsive PV simulator that can be treated as a real PV module in most situations"--Abstract, page iii.
