In this paper, we study simultaneous wireless information and power transfer (SWIPT) systems employing practical non-linear energy harvester (EH) circuits. Since the voltage across reactive elements of realistic EH circuits cannot drop or rise instantaneously, EHs have memory which model with a Markov decision process (MDP). Moreover, since an analytical that accurately models all effects unavo...

A reconfiguration technique using a switched-capacitor (SC)-based voltage equalizer differential power processing (DPP) concept is proposed in this paper for photovoltaic (PV) systems at cell/subpanel/panel-level. The active diffusion charge redistribution (ADCR) architecture increases the energy yield during mismatch and adds boosting capability to PV system under no by connected available cel...

Robust control and maintenance of the grid relies on accurate data. Both PMUs and state estimators are prone to false data injection attacks. Thus, it is crucial to have a mechanism for fast and accurate detection of an agent maliciously tampering with the data—for both preventing attacks that may lead to blackouts, and for routine monitoring and control tasks of current and future grids. We pr...

Wireless power transfer (WPT) has attracted an ever increasing interest from both industry and academics over the past few years. Its applications vary from small power devices such as mobile phones and tablets to high power electric vehicles, and from small transfer distance of centimeters to large distance of tens of centimeters. In order to achieve a high efficiency WPT system, each circuit ...

In this paper basic CAM (Content Addressable memory) cell performs match and mismatch operation. CAM provides fast data search operation and it is also used as search engines. The CAM cell comprises of NAND cell block of array (1x8) and NOR cell block of array (4x32). Here in this paper 45nm technology (transistor sizing) with the supply voltage of 1V is used. The data stored in the CAM cell wi...

In the field of electrical solar power conversion EMC is of topical importance. In common single-phase inverter applications the current of the solar array shows a pronounced ripple. This entails two significant disadvantages: Reduced over-all efficiency due to dynamic maximum power point mismatch and reduced lifetime of the panels due to additional component stress. Furthermore, the output of ...

As one of themost developed provinces in China, Jiangsu Province has been actively developing bio-energy in order to deal with its electricity supply shortage. By the end of 2010, there are 12 grid-connected strawbased power plants, but only two of them are profitable in this province. This paper presents a simple and detailed method for estimating the cost of straw-based power generation with ...

This work presents a novel carrier frequency offset (CFO) estimation algorithm, based on pseudo-CFO (P-CFO), to estimate the CFO value under the conditions of I/Q mismatch for direct conversion structures with 2-dB gain error and 20-deg. phase error in frequency selective fading channels. To circumvent CFO with I/Q mismatch, the proposed P-CFO algorithm rotates three training symbols by adding ...
