Abstract
The increase demand of electrical energy due to the industrial development and world population has made the traditional energy resources entered the age of insufficiency. Recently, an increase attention has been given to the renewable energy sources, especially photovoltaic (PV) energy systems as an alternative energy resource available everywhere in Egypt. And offer substantial advantages over conventional power resources such as reliability, low
maintenance cost, no fuel cost, reduced sound pollution, safety and high performance. DC-DC boost converter is inserted between the source and the load as power conditioning unit to regulate and boost up photovoltaic voltage to desired output voltage. But the conventional boost converter give output voltage not exceeds about twice of the input for stable operation, this not sufficient for distribution level voltage. So, high gain DC/DC converter is ideal solution to achieve high voltage level at the output with high efficiency to convert the electrical power to useable form. There are a lot of topologies of high gain DC/DC converter that used with PV. In this thesis introduces a proposed non isolated high gain DC/DC converter used to convert low voltage solar PV panels to distribution level voltage. To do this, a converter used a single switch with switched inductor technique that is able to produce high gain power transmission and continuous input current. This thesis the steady state analysis and operation modes of the proposed converter are explained in detail for continuous conduction mode (CCM) and discontinuous conduction
mode (DCM) operation. Also, the mathematical analysis implementation and voltage gain derivation is carried out for the proposed converter. Computer simulations are carried out for the proposed topology by Matlab/Simulink
software. The prototypes of the proposed converter for CCM and DCM cases were built and tested in the laboratory. A DSP 1104 platform was used for evaluation board closed loop performance and open loop performance in order to verify the theoretical analysis. The
experimental setup and hardware implementation are described. Several of experimental results for the proposed topology are included and discussed. The simulation and experimental results
of the proposed converter are studied for closed loop case with static load by using resistive load and dynamic load by using separately excited DC motor.
The proposed converter is compared with other recent converters and it is cleared from this comparison the advantages of the proposed with respect to others that shows the proposed
converter has lower compensative components (capacitors and inductors), lower voltage stress for semi-conductor device (switch and diodes) and higher efficiency. The simulation and experimental results are proved these advantages for the proposed converter and in good agreement.
