Applied Digital Control for Localization of the Maximum Power of Photovoltaic Generators
This paper describe the development of a digital control applied in energy generation using photovoltaic cells in joint with the other generator system (a diesel generator, for example) the technique consist in the localization of the maximum power point (pick power tracking) of photovoltaic cells utilizing digital control. Its application is attractive to isolated load system, such as isolated communication system and data transmission located in remote Amazon areas
Dc-Dc converters with FPGA control for photovoltaic system
The paper introduces on operating principle of power management of photovoltaic system with maximum power tracker control to achieve the maximum efficiency of such systems. The paper presents different topologies of basic photovoltaic concepts with DC-DC converters including control design of maximum power tracker by Matlab-Simulink. The paper will be present different topologies of converter concepts that improve the total efficiency value. PWM controlling of such sophisticated system can be achieved by field-programmable-gate-array (FPGA) that more details of set up PWM signals due to FPGA technologies is shown in this paper.
Approximate analytical solution of generalized diode equation
An approximate but very precise analytical solution is derived of a generalized diode equation. This solution can be used in the theory of semiconductor diodes, photodetectors, solar cells, FETs (field-effect transistors), Gunn domain, and other areas of device physics. The proposed analytical solution is in excellent agreement with the results of the numerical calculation. >
