A Review Of Parallel Operation Of Active Power Filters In The Distributed Generation System, Shafiuzzaman Khadem, Malabika Basu, Michael Conlon
A Review Of Parallel Operation Of Active Power Filters In The Distributed Generation System, Shafiuzzaman Khadem, Malabika Basu, Michael Conlon
Dr. Shafiuzzaman Khan Khadem
In this paper a technical review of parallel operation of Active Power Filter (APF) for harmonic power compensation in distributed generation (DG) network has been presented. Controlling methods and connection topologies with their pros and cons are described. Recent improvements in controlling and future trends for the application of APFs in distributed mode are also identified.

Partial shading in thin film solar panels can result in reverse bias stress across shaded cells. Therefore, it is important to understand the effect of such reverse stress in commercially competitive PV technologies such as CIGS. In this paper, we systematically investigate the effect of moderate reverse bias on solution-processed CIGS solar cells. We subject the solar cells to varying degrees of reverse biases and continuously monitor the impact of the stress on dark current. We also explore the relaxation behavior of dark current following passive storage and the long term effect of the shadow stress on power output of …
Evolution Of A Folded Floating-Gate Differential Pair, Bradley Minch
Evolution Of A Folded Floating-Gate Differential Pair, Bradley Minch
Bradley Minch
The author presents a folded floating-gate MOS (FGMOS) differential pair circuit that is capable of simultaneously providing a rail-to-rail common-mode input voltage range and a rail-to-rail output voltage swing with a low power-supply voltage. In this configuration, the voltage drop across the bias current source is folded up into the same range over which the output voltages swing, facilitating low-voltage operation. The floating-gate charge can be used to trim out the offset voltage of the differential pair and to reduce the required power-supply voltage for a given bias current level. The author provides both a qualitative description of how the …

The Impact Of Quality Management Systems During A Pebble Bed Modular Reactor Project : A Case Study, Lwandiso Zamxaka

In the nuclear industry, Quality Management Systems are extremely important,especially if one wishes to improve public acceptance of radioactive solutions.There is normally minimum communication between the public and scientists,especially in nuclear science. People are not comfortable with nuclear technology,based on the past history of the Chernobyl catastrophe. Consequently, it is difficult to discuss important and sensitive issues like disposing of nuclear waste. Quality Management Systems can improve public confidence and communication. Integrated Management Systems in the project planning stage of the project can be a proactive step towards preventing unnecessary delays and costs. There is a perception that quality is …
