Design and Realization of Sliding Mode Control DC to DC Boost Converter of photovoltaic systems

This research is a study of a new control method of switching non-isolated dc-dc boost converters used in Photovoltaic systems. This method is called Sliding Mode Control (SMC), which is considered as an alternative to other methods, to keep a stable and constant output voltage by changing the input voltage and load current. The analyzing method of the switching nonisolated dc-dc boost converters using SMC shows the same complexity of Clasic circuits, but it gives an increasing potential and a high-dynamic response to ensure a constant output voltage reaches to 40volt by changing the input voltage in the range (16-21volt) and the load (8-13Ω). Methods to measure the accuracy, error, and efficiency of maximum power point trackers (MPPT) have been identified and presented in a schematic way, together with definitions of terms and calculations.
