For green energy micro-grid applications, it is crucial to have a step-up converter that can produce a wide range of voltages. This converter is necessary to match the low voltage output of the micro-grid with the DC-bus voltage and must have continuous input current. A new ultra-gain step-up converter with continuous input current, is proposed to achieve this objective. The proposed converter is a non-coupled inductor-based, non-isolated boost converter with continuous input current which is suitable to operate at a high voltage suitable for green energy based micro-grid applications.

This paper introduces a reference-free, scalable, and energy-efficient dynamic voltage scaler (DVS) that can be reconfigured for multiple outputs. The proposed DVS employs a novel swapping switched-capacitor (SSC) technique, which can generate target output voltages with higher resolution and smaller ripple voltages than the conventional voltage scalers based on switched-capacitors. The proposed DVS consists of a cascaded 2:1 converter based on swapping capacitors, which is essential to achieve both very small voltage ripple and fine-grain conversion ratios. One of the serious drawbacks of the

In Multi-Level-Cell (MLC) NAND flash memory, cell-to-cell interference (CCI) and retention time have become the main noise that degrades the data storage reliability. To mitigate such noise, a relative precision loss (RPL) nonuniform reference voltage sensing strategy is proposed in this paper. First, based on the NAND flash channel model with CCI and retention noise, we simulate the data storage process of MLC NAND flash by Monte Carlo method, and find that the threshold-voltage of each disturbed storage state shows approximately to be Gaussian distributed. Then, by Gaussian approximation, th

This paper deals with the problem of the voltage profile optimization in a distribution system including distributed energy resources. Adopting a centralized approach, the voltage optimization is a non-linear programming problem with large number of variables requiring a continuous remote monitoring and data transmission from/to loads and distributed energy resources. In this study, a recently-proposed Jacobian-based linear method is used to model the steady-state operation of the distribution network and to divide the network into voltage control zones so as to reformulate the centralized opt

The impact of unbalanced power supply voltages on power derating, increases in current values and the heat released from electrical machines and devices is typically analysed in quasi-steadystate operation using sequence components.

A voltage balance control strategy based on the fuzzy adaptive PI (Proportional Integral control) is proposed to address the problem of unbalanced capacitor voltage on the DC side of cascaded H-bridge static var generators (SVG). In the control strategy, fuzzy control is introduced based on PI control. A duty ratio correction is added to all levels’ public active power duty ratios, thereby realizing the balance of DC-side voltages at all levels. A test was conducted by building a single-phase three-H-bridge unit cascaded SVG simulation platform. The results show that the DC-side voltage balanc

Load break switches (LBSs) are common inside metal clad switchgear assemblies where space is a limiting factor. SF6 is usually used in this application due to its superior electrical characteristics, but is unfortunately also a strong greenhouse gas. Therefore development of new products, utilizing air which is an environmental friendly alternative, is in progress. Since air has much lower dielectric strength than SF6, the main challenge with this is therefore to reduce the size. Compact SF6 products have created a retrofit market, and in many existing installation sites larger products will n

With the continuing growth in energy consumption worldwide, the move towards a European wide super grid will result in significant changes in how modern transmission and distribution networks are operated. Fundamental to this is the need to accurately know or determine the available ampacity of high voltage cable circuits, because huge bulk power volumes need to be transmitted between maritime nations through dc power cables. Therefore, an accurate cable rating becomes paramount towards an efficient and safe operation of transmission networks, while the finance for large scale network construc

AbstractThis chapter introduces the topic decibel in a compact form. Decibel is defined as the ratio of two quantities, typically power, voltage, or current. In the field of EMC, the decibel must be understood. One advantage of decibels is that a gain of 10 dB means a gain of 10 dB for current, voltage, and power likewise. This fact helps to prevent misinterpretations and helps to simplify things. This is the main reason why EMC and high-frequency system engineers like to work with decibels.This chapter assumes that values of voltages V [V], currents I [A], power P [W], electric field strength

This paper addresses the assessment of the corrosion risk of a pipeline due to alternating currents. The state of the art technique is the use of coupons, which simulate a coating fault and which allow to measure the ac-current density and also to evaluate corrosion products and pits. Recently, different criteria to assess the corrosion risk have been proposed that are based on the ratio between ac- and dc-current density or the instantaneous off-potential (high-speed off-potential measurement) measured on a coupon. Furthermore, the charge needed to oxidize corrosion products (under alkaline c

The objective of paper is to study the effect of fluctuating AC interference phenomenon (AC interference time duration and level of AC interferences) on the corrosion risk of pipelines. This fluctuation typically represents the actual condition experienced by the pipeline but is not entirely captured or discussed in current guidelines or standards (e.g., the EN 15280:2013) which operates only with average values over a representative period of time. This study involves systematic laboratory investigations of fluctuating AC voltage levels (0, 6, 25, and 40 V) for various time durations and the

The increasingly strict air emission regulations may require implementing Non-Selective Catalytic Reduction (NSCR) systems as a promising emission control technology for stationary rich burn spark ignition engines. Many recent experimental investigations that used NSCR systems for stationary natural gas fueled engines showed that NSCR systems were unable to consistently control the exhaust emissions level below the compliance limits. Modeling of NSCR components to better understand, and then exploit, the underlying physical processes that occur in the lambda sensor and the catalyst media is no
