Abstract:

A new Cuk converter with high step-down ratio was proposed. The operating principle and operating mode of the new Cuk converter were analyzed in detail and the EL model of the new Cuk converter was established. Based on passivity-based control theory, a passivity-based controller of the new Cuk converter was designed by the method called damping injection. The controller can enable the new Cuk converter achieve good dynamic and static performance and robustness to the load. Compared with Buck converters, the new Cuk converter has a higher step-down capability and a smaller ripple of the input current. Simulation results show that the new Cuk converter is feasible.

Abstract:

This paper introduces a two-switch high gain non-isolated Cuk converter which can be used as a high gain DC-DC converter in renewable energy, such as photovoltaic and fuel cell, applications because their output is low. As the conventional, the proposed Cuk converter provides negative output voltage but with a higher voltage in magnitude. The main advantage of the proposed converter is having lower voltage stress with the ability to maintain a higher voltage gain. By combining a switched-inductor and a switched-capacitor into the conventional Cuk converter, the proposed Cuk converter has the ability to reach 13 times the input voltage for a duty cycle D of 0.75. Also, by attaching more switched-inductors to the proposed Cuk converter, more voltage gain can be achieved. A complete theoretical analysis of the Continuous Conduction Mode (CCM) of the proposed Cuk converter is presented and the key aspects of the circuit design have been derived. Also, a comparison in terms of voltage gain and voltage stress between the proposed Cuk converter and Cuk converters using other techniques is presented. The proposed Cuk converter has been designed for 100W rated power, -152V output voltage, 50kHz switching frequency, and 75% duty cycle. The presented converter is simulated in Matlab/Simulink and the results are discussed.

Abstract:

Maximum Power Point Tracking (MPPT) is a method that can be used to optimize the electrical power output from solar panels. The performance of the MPPT method on solar panel systems can be influenced by many variables. One of them is the selection of a DC-DC power converter. DC-DC-DC Converter is a component that is used to optimize the performance of solar panels. Several types of DC-DC Converter are Buck, Buck-Boost, Single Ended Primary Inductance Converter (SEPIC), and CUK. Each converter has a different effect on solar panels output power. In order to observe and make a comprehensive analysis, simulations are performed through PSIM (Power Simulator) software on the performance of several DC-DC Converters that use Flower Pollination Algorithm (FPA) as the MPPT algorithm. Variables that observed are the output power characteristic, the response of the voltage-current ripple signal, and the accuracy of the converter in the process of reaching the maximum power point condition. As a result, CUK converter can obtain the highest value of solar panel output power, 145.02 W. A low ripple level with a stable power value response is entirely generated by CUK and SEPIC Converter. Overall, for this system, the CUK converter has better performance than the other converters.

To be used for voltage regulator, An AC-AC direct converter with small bulk has been researched. The paper has proposed an isolated Cuk Three-Level AC-AC Converter. It is produced by applying TL AC switch unit in Isolated Cuk converter which is put forward by Slobodan Cuk. Because the two-level converter usually isn’t used in high voltage and heavy load situation, the paper proposed the cascaded type of isolated Cuk AC-AC converter. Besides, the operating principle and the control strategy of isolated Cuk Three-Level AC-AC Converter are investigated. Transient voltage feedback control is used in the converter and principle diagram of control circuit is given.

Abstract:

The wide range of step-up and step-down input-output voltage characteristic of the Cuk converter makes it a good candidate to interface photovoltaic arrays in both classical and distributed maximum power point tracking systems. Because its two inductor structure, Cuk converters have continuous input and output currents, which reduce the additional filtering elements usually required for interfacing dc/dc converter topologies. However, PV systems based on Cuk converters usually do not provide formal proofs of global stability under realistic conditions, which makes impossible to ensure a safe operation of the PV installation. Therefore, this paper proposes a high performance sliding-mode controller for PV systems based on Cuk converters, which regulates the PV voltage in agreement with the commands imposed by a MPPT algorithm, rejecting both load and environmental perturbations, and ensuring global stability for real operation conditions. Finally, the performance of the regulated PV system is tested using both simulations and experiments.

Abstract:

A nonisolated three-port DC–DC converter based on Cuk topology (NI-TPC) to handle the renewable sources (RS) is proposed in this paper. This converter includes two unidirectional input ports accommodating both a fuel cell (FC) and photovoltaic (PV) cell; and one output port with DC load. Due to the inductors at all the ports, it claims the advantage of continuous input and output currents. Additionally, it uses less number of switches, diodes and inductors compared with conventional ‘n-1’ separate Cuk converters. Synthesis procedure for a generalized n-port DC–DC structure is explained. The derivation law based on conventional Cuk converter, operating principle, design calculation, and analysis are presented in detail, and then the analysis is validated through simulation and a 100W prototype, verifying the performance of the proposed NI-TPC converter.

Abstract:

In this paper, performance enhancement of Photovoltaic (PV) system is done by a passive lossless soft switched noninverting Cuk converter with Perturb and Observe (P&O) based maximum power point tracker (MPPT) that uses a hybrid sliding mode controller (SMC). In the proposed Cuk converter, conduction losses, voltage stress and switching losses are mitigated by introducing a snubber cell. Therefore, Cuk converter efficiency is improved which in turn increases efficiency of PV system. Peak power is continuously collected from PV panel and optimal operating point is detected using hybrid SMC based MPPT method. Performance analysis of the modified Cuk converter and conventional converter is illustrated by simulation and experimental methods for various irradiation and temperature changes. Experimental results verify the performance of modified Cuk converter implemented in PV system.

This work presents the study and implementation of an ac-dc Ćuk converter based on the three state switching cells applied in charger stations for electric vehicles. This converter has, as main characteristics, reduction of conducting power losses in the semiconductors, a single stage topology and current source behavior for both input and output terminals. As drawbacks, the topology presents: the voltage across the semiconductors is equal to the sum of the input and the output voltages, and a difference between the current values through the semiconductors caused by an inappropriate layout of the power prototypes or by a lack of symmetry between the control signals. The analysis of the converter is made through the qualitative and quantitative studies, beyond the analysis of the semiconductor losses which are presented as well. The current and voltage of the battery are controlled by the average current mode technique, which consist in a fast current control loop if compared with the terminals battery voltage control loop. The topology is design for 1 kW output power, 220 V in input voltage and 162 V in the output terminals (12 batteries in series connection). Experimental results for resistive load, as well batteries, are shown in order to verify the functionalities of the topology and its characteristics.

Abstract:

Lighting consumes approximately 20-25% of the energy produced worldwide. LED based lighting is rapidly becoming the preferred choice over incandescent and fluorescent based lighting. LEDs have advantages such as high efficacy, long operating lifetime and excellent lumen maintenance. Therefore, to gain benefits from LEDs for lighting purposes, they must be driven with efficient drivers which maintain high LED efficacy and long LED lifetime. A review of existing LED drivers is done, and their advantages and drawbacks are identified. Existing fault-tolerant drivers are also reviewed. Several dimming methods and their effects on the LED efficacy and lifetime are investigated. As a result, a converter with coupled inductors, suitable as an LED driver which has high efficiency and can maintain high LED efficacy, incorporated with a high efficiency dimming method, is chosen. For the proposed LED driver, a comprehensive analysis on the effects of coupling type and coupling coefficient on converter performance is done. This is carried out to establish the best coupled inductor structure and coupling coefficient, for the proposed LED driver. The coupled inductor obtained is used to achieve high LED efficacy and also used to eliminate the need for an output filtering capacitor. This results in a highly compact, high efficiency and low cost LED driver. A lossless method of LED string current sensing is proposed, so that driver efficiency is not negatively impacted. The LED driver and a digital control system are designed, with the fault-tolerant feature incorporated. The LED driver and the control system are simulated and practically implemented. The results obtained show excellent LED driver performance. The fault-tolerant feature can enable the driver to operate under fault conditions, saving repair costs and down time. Additionally, a novel digitally controlled LED driver, which can drive several independent multiple LED loads, is proposed. This novel driver is simulated and practically implemented; with the results showing excellent driver performance. The novel LED driver can simplify and reduce costs of existing LED lighting systems.

Abstract:

Growing concerns about climate change have led to the world experiencing an unprecedented push towards renewable energy. Economic drivers and government policies mean that small, distributed forms of generation, like solar photovoltaics, will play a large role in our transition to a clean energy future. In this thesis, a novel DC-DC converter known as the Coupled Inductors Combined Cuk-SEPIC' (CI-CCS) converter is explored, which is particularly attractive for these photovoltaic applications. A topological modification is investigated which provides several benefits, including increased power density, efficiency, and operational advantages for solar energy conversion. The converter, which is based on the combination of the Cuk and SEPIC converters, provides a bipolar output (i.e. both positive and negative voltages). This converter also offers both step-up and step-down capabilities with a continuous input current, and uses only a single, ground-referenced switching device. A significant enhancement to this converter is proposed: magnetic coupling of the converter's three inductors. This can substantially reduce the CI-CCS converter's input current ripple - an important benefit for maximum power point tracking (MPPT) in photovoltaic applications. The effect of this coupling is examined theoretically, and optimisations are performed - both analytically and in simulations - to inform the design of a 4 kW prototype CI-CCS converter, switched at a high frequency (100 kHz) with a silicon carbide (SiC) MOSFET. Simulation and experimental results are then presented to demonstrate the CI-CCS converter's operation and highlight the benefits of coupling its inductors. An efficiency analysis is also undertaken and its sources of losses are quantified. The converter is subsequently integrated into a domestic photovoltaic system to provide a practical demonstration of its suitability for such applications. MPPT is integrated into the CI-CCS DC-DC converter, and a combined half bridge/T-type converter is developed and paired with the CI-CCS converter to form an entirely transformerless single-phase solar energy conversion system. The combination of the CI-CCS converter's bipolar DC output with the combined half bridge/T-type converter's bipolar DC input allows grounding at both the photovoltaic panels and the AC grid's neutral point. This eliminates high frequency common mode voltages from the PV array, which in turn prevents leakage currents. The entire system can be operated in grid-connected mode - where the objective is to maximise power extracted from the photovoltaic system, and is demonstrated in stand-alone mode - where the objective is to match solar generation with the load's power demands.

A topologia apresentada é baseada na combinação do conversor Cuk com uma estrutura de indutores chaveados para obtenção de um maior ganho estático e um circuito inversor em ponte completa conectado à rede. A estrutura de indutores chaveados apresentada nesse trabalho reduz esforços de tensão e corrente nas chaves semicondutoras. Com o objetivo de facilitar o controle, a etapa CC do microinversor opera em modo de condução descontínua (DCM). Para injetar corrente senoidal com baixa distorção harmônica à rede, é aplicado às chaves semicondutoras da etapa CC uma modulação por largura de pulso senoidal (SPWM). As chaves semicondutoras do circuito inversor em ponte completa são comandadas na frequência da rede, reduzindo perdas por chaveamento. Por se tratar de uma topologia inédita, são apresentados os modos de operação e a análise matemática do conversor CC-CC Cuk com alto ganho estático. Posteriormente, são realizadas a análise teórica e a estratégia de controle do microinversor proposto. Os resultados experimentais são expostos para discutir o funcionamento da topologia proposta, através de simulações e da implementação de um protótipo de 180 W.
The development of a novel single stage microinverter is proposed. The presented topology is based on the combination of the Cuk converter with a switched inductor structure to obtain a higher static gain, and a full-bridge inverter circuit. The presented switched inductor structure reduces voltage and current stresses on the power switches. In order of simplify the control, the stage CC of the microinverter operate in discontinuous conduction mode (DCM). To inject sinusoidal current with low harmonic distortion to the grid, a sinusoidal pulse width modulation (SPWM) is applied in the power switches. The switches of the full-bridge invertes are commanded in low frequency, in order to reduce switching losses. Operation modes and math analysis of the novel CC-CC converter are presented. Moreover, the math analysis and control strategy of proposed microinverter topology are exposed. Furthermore, experimental results are performed to analyze the proposed topology operation, by software simulations and implementation of a 180 W prototype.

O desenvolvimento de um conversor CC-CC de três portas é proposto neste trabalho. Através da combinação de um conversor bidirecional Ćuk e um transformador de alta frequência com um circuito retificador em ponte completa, duas portas de energia não isoladas e uma porta de energia isolada são obtidas. Um circuito LC série ressonante é empregado, resultando em comutação suave nos interruptores de potência.

Além disso, os interruptores de potência são compartilhados nas etapas de operação, reduzindo o número de componentes ativos. Regulação de suas portas é realizada para aplicações com elementos armazenadores de energia.

Abstract:

Drawing on insights from the previous chapters, this chapter details the various rifts in Muslim America that cut across generational, gender, ethno-racial, and immigrant–convert categories. It argues that the narrative that calls for building a community indexes a rapprochement between the constituting groups of Muslim America. This rapprochement is taking place in and through the process of constructing a coalitional sociopolitical identity inspired by models from American society and from the Islamic concept of ummah. The chapter argues that the challenges that Muslims encounter in a post-9/11 America have acted as a catalyst for this process of coalitional community building, but it is a work in progress.

Yet, the literature on Indian multilateralism lags, focusing disproportionately on India’s ostensibly obstructionist tendencies without adequately contextualizing why India behaves this way. There has been no serious exploration of how India concretely negotiates multilateral issues. In this book, Karthik Nachiappan investigates how India negotiates international rules covering issues like climate change, nuclear disarmament, tobacco control and international trade. By unpacking these negotiations, he shows that India’s multilateral persona is more nuanced than is generally understood. When interests converge, Indian negotiators are willing to shape and ratify international agreements, conceding when necessary to cut deals and make compromises.

Abstract:

Core Logic has unusual philosophical, proof-theoretic, metalogical, computational, and revision-theoretic virtues. It is an elegant kernel lying deep within Classical Logic, a canon for constructive and relevant deduction furnishing faithful formalizations of informal constructive mathematical proofs. Its classicized extension provides likewise for non-constructive mathematical reasoning. Confining one’s search to core proofs affords automated reasoners great gains in efficiency. All logico-semantical paradoxes involve only core reasoning. Core proofs are in normal form, and relevant in a highly exigent ‘vocabulary-sharing’ sense never attained before. Essential advances on the traditional Gentzenian treatment are that core natural deductions are isomorphic to their corresponding sequent proofs, and make do without the structural rules of Cut and Thinning. This ensures relevance of premises to conclusions of proofs, without loss of logical completeness. Every core proof converts any verifications of its premises into a verification of its conclusion. Core Logic makes one reassess the dogma of ‘unrestricted’ transitivity of deduction, because any core ‘restriction’ of transitivity ensures a more than compensatory payoff of epistemic gain: A core proof of A from X and one of B from {A}∪Y effectively determine a proof of B or of absurdity from some subset of X∪Y. The primitive introduction and elimination rules governing the logical operators in Core Logic are subtly different from Gentzen’s. They are obtained by smoothly extrapolating protean rules for determining truth values of sentences under interpretations. Core rules are inviolable: One needs all of them in order to revise beliefs rationally in light of new evidence.
