Ask ChatGPT about the research

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.

The DC sources like fuel cells, solar cells, storage units need to raise its output voltage in order to match load requirements. So often these systems are equipped with Power Electronics techniques in general and DC-DC booster converters in partic ular. The paper provides the mathematical model and algorithm for designing the booster converter with selected values in order to define the values of the most important parameters of its components including inductor parameters. Based on the developed algorithm, a simulation of the system is conducted in MATLAB / Simulink environment to analyze the impact of changing the inductor inductance on booster performance. Also the paper includes the mathematical model and algorithm for designing the booster inductor in terms of material, conductor type and shape of core and number of windings. Based on the design results, the inductor has been implemented completely in the laboratory. The inductance of the implemented inductor has been measured using a number of measuring methods to make sure of its value and match it with the theoretical values of design. Finally, the developed algorithm has been translated into a program in an environment Matlab / GUI , with which several computer tests have been performed.
This research deals with improving the efficiency of solar photovoltaic (PV) power systems using a Maximum Power Point Tracker controller (MPPT controller), based in his work on the Maximum Power Point Tracking techniques via the direct control met hod. Which used to control the duty cycle of DC-DC Voltage Converter, to achieve the photovoltaic system works at a Maximum Power Point under different atmospheric changes of the solar insolation and ambient temperature. In this context, our work is focused on the simulation of the components of the power generating system, such as the photovoltaic system, DC-DC Boost Converter and a MPPT controller in Matlab/Simulink environment. The simulating of the MPPT controller was based on several algorithms such as: Constant Voltage algorithm, Perturb and Observe algorithm and Incremental Conductance algorithm by using Embedded MATLAB function. The simulation results showed the effectiveness of the MPPT controller to increase the photovoltaic system power compared with non-use of a MPPT controller. The results also showed the best performance of MPPT controller based on Perturb and Observe and Incremental Conductance algorithm, compared with constant voltage algorithm in tracking the Maximum Power Point under atmospheric changes.
