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 particular. 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 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 sta
ble 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.
This research introduce a detailed study of designing high efficiency
100W DC-DC Boost Converter for standalone photovoltaic system
and practical implementation of it’s circuit, by selecting the best
elements with less loss in power in the tow des
igns,to reach the best
efficiency by theoretical calculations and simulation in ORCA, and
compare the results with the practical implementation. Also this
research shows a study of effect of frequency variation on the
efficiency of the converter.
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.
The main goal of this search is to design maximum solar power batteries charging
system, Maximum power point tracking (MPPT) system is used in the photovoltaic (PV)
system consisting of a buck-boost Direct Current DC/DC converter, which is controll
ed by
a microcontroller unit, The microcontroller is programmed with a simple and reliable
MPPT called Incremental Conductance (InCond).
The designed battery charger was tested, and the results obtained had insured about
the permanent control on the battery charging.
Comparison study was done, with PWM solar charger controller, it was obvious by
The experimental results, that the battery get charged in a very short time period
considering of the solar sun light hours per day, and the characteristics of the used solar
panel, which confirm the reliable performance of the suggested charging system.
This paper offer a designed module for buck-boost DC-DC converter, able to solve
unsteady charging voltage problem, due to constant decreasing scale of transformers and
grid or solar panel voltage drop, this module has been designed using fuzzy log
ic in PWM
control and simulated in matlab and all test and its results illustrated the suitable figure.
