Synchronous link converter var compensator (SLCVC)
This document discusses a synchronous link converter var compensator (SLCVC). The SLCVC uses selective harmonic elimination techniques to eliminate the 5th, 7th, and 11th harmonics. The main compensator controls the fundamental component of compensator current by controlling the DC link voltage. An auxiliary converter provides online elimination of higher order harmonics generated by the main compensator. Simulation studies were carried out to evaluate the compensator's performance. Experimental testing verified the control strategy by operating the SLCVC as a load compensator and changing the reference DC link voltage. The SLCVC provided superior performance through effective combination of high power low frequency and low power high frequency switching devices.
A high step down transformer less single-stage single-switch acdc converter
This paper presents a high step-down transformerless single-stage single-switch AC/DC converter suitable for universal line applications from 90-270Vrms. The converter integrates a buck-type power factor correction cell with a buck-boost DC/DC cell, allowing part of the input power to transfer directly to the output after the first power processing stage. This direct power transfer feature, along with shared capacitor voltages, allows for efficient power conversion with high power factor and low voltage stress on the intermediate bus and output, without requiring a high step-down transformer.

This document presents a new design methodology for single-switch inverters, like Class E inverters, that enables them to maintain zero-voltage switching over a wide range of resistive loads. Traditionally, Class E inverters are highly sensitive to load variations and only maintain zero-voltage switching over a narrow load resistance range. The proposed methodology allows for designing Class E and related inverters that can efficiently operate over a 12:1 load resistance range. This is demonstrated experimentally with a Class E inverter design operating over a 12:1 resistance range with an 8:1 output power variation and a 25W peak power.

An investigation on lte mobility management
LTE uses the Mobility Management Entity (MME) to handle mobility management differently than 3G networks. The MME is responsible for mobility management and is connected to evolved Node B cells, which are grouped into Tracking Areas (TAs). TAs are further grouped into TA Lists (TALs). When a User Equipment moves out of its current TAL, it reports its new location to the MME. This paper investigates the performance of LTE paging, where the MME pages cells, TAs, or TALs to locate a UE, and provides guidelines for the best paging sequence.

This document provides an abstract for a paper that proposes a new problem called Approximate Membership Localization (AML) for dictionary-based entity recognition. AML aims to locate non-overlapping substrings in a document that approximate true matches, without generating redundant overlapped substrings like Approximate Membership Extraction (AME) does. The paper proposes an algorithm called P-Prune that prunes redundant matched substrings to perform AML more efficiently. Experimental results on real-world datasets demonstrate P-Prune's efficiency over baselines and show that AML outperforms AME, including in a proposed web-based join framework application.

This document analyzes distance-based location management schemes (DBLMS) in wireless communication networks. A Markov chain mobility model is developed to describe a mobile terminal's movement in a 2D cellular structure. Classical renewal theory is used to analyze the expected number of paging area boundary crossings and cost of the distance-based location update method for two different call handling models. The analysis makes it possible to find the optimal distance threshold that minimizes the total cost of location management in a DBLMS.

The document discusses an adaptive voltage control method for the DC/DC boost stage in photovoltaic converters that allows for a smaller input capacitor. Traditionally, PV systems use a large input capacitor for adequate voltage regulation to maximize power from the solar array. However, with a smaller capacitor the nonlinear characteristics of the PV array cause the voltage regulation performance to highly depend on the operating point. The paper analyzes these nonlinearities, proposes an adaptive control based on linearizing around the operating point, and validates the control through experiments on a commercial converter with a 40 μF capacitor connected to a 4 kW solar array.

The document describes a dual-mode full-bridge series resonant DC-DC converter that can operate at either a variable switching frequency or a fixed switching frequency with phase-shifted pulse width modulation to regulate the output voltage over a wide range of loads. The converter uses a series resonant tank consisting of an inductor and capacitor to achieve soft switching and zero voltage switching of the transistors. It can operate in a frequency modulation mode at high loads by varying the switching frequency, or in a phase modulation mode at light loads using a fixed high switching frequency and varying the duty cycle through phase-shifted pulse width modulation. This dual-mode operation provides high conversion efficiency across a wide range of loads.

Design & Simulation of 3-Phase, 27-Level Inverter with Reverse Voltage Topology
Multilevel inverters have been widely accepted for high-power high-voltage applications. Their performance
is highly superior to that of conventional Seven-level inverters due to reduced harmonic distortion, lower
electromagnetic interference, and higher dc link voltages. In this paper, a new topology with a
reversing-voltage component is proposed to improve the multilevel performance. This topology requires fewer
components compared to existing inverters (particularly in higher levels) and requires fewer carrier signals
and gate drives. Therefore, the complexity is greatly reduced particularly for higher output voltage levels. The
Proposed 27-level inverter is modeled and simulated in Matlab 2012b using Simulink and Sim Power

Speed Control Of Separately Excited Dc Motor Using A High Efficiency Flyback ...
This paper deals with Speed control of separately excited DC motor using flyback converter with a new non complementary active clamp control method to achieve soft switching and high efficiency for heavy motor load and light load conditions. This is quite attractive for low power application with universal ac inputs, such as external adaptors. With the proposed control technique, the energy in the leakage inductance can be fully recycled. The soft switching can be achieved for the main switch and the absorbed leakage energy is transferred to the output and input side. In the Proposed model the resistive and DC motor is connected to flyback converter and it is simulated with different nominal voltages and rated speed is controlled at different levels for the N-type active clamp flyback converter and P-type active clamp flyback converter respectively. N-type active clamp flyback converter is suitable for high speed variation applications and P-type active clamp flyback converter is suitable for low speed variation applications.

A Resonant Converter with LLC for DC-to-DC Converter Based Applications
This document discusses a current mode control scheme for LLC series resonant DC-to-DC converters used for electric vehicle battery chargers. The proposed current mode control employs feedback from the resonant tank current to nullify effects of changes in power stage dynamics, improving performance over conventional voltage mode control. The LLC converter has multiple resonant modes depending on operating frequency and load. Experimental results show the current mode control achieves 97.96% peak efficiency for a 6.6 kW, 390V to 250-450V converter. Future work will focus on design optimization and a simpler design procedure.

Analysis of a fifth order resonant converter for high-voltage dc power supplies
- 1. ANALYSIS OF A FIFTH-ORDER RESONANT CONVERTER FOR HIGH-VOLTAGE DC POWER SUPPLIES ABSTRACT: Power transformer is one of the most complex parts of power converters. The complicated behavior of the transformer is usually neglected in the power converter analysis and a simple model is mostly used to analyze the converter. This paper presents a precise analysis of a fifth-order resonant converter which has incorporated the resonant circuit into the transformer. The derived model, which is based on the accurate model of the power transformer, can fully predict the behavior of the fifth-order resonant converter. The proposed fifth-order resonant converter is able to effectively reduce the range of phase-shift angle from no load to full load for a fixed-frequency phase-shift control approach. Therefore, the converter is able to operate under zero voltage switching during entire load range with a fixed-frequency control method. Also, the proposed converter offers a high gain which leads to a lower transformer turns ratio. A 10-kVDC, 1.1kW prototype has been prepared to evaluate the performance of the proposed converter. The experimental results exhibit the excellent accuracy of the proposed model and the superiority of the performance compared to the lower order resonant converters, especially for high-voltage applications.
