Abstract:

Converter plays a vital role in modern transferable electronic devices and systems. In the battery operated transferable devices, the battery supplies an input voltage to the converter which in turn converts into the desired voltage. Buck-boost, Cuk, SEPIC and Zeta converter are meeting the operational requirements of DC-DC converters. The DC-DC converters are used in both buck function as well as boost function. But the advantage of Zeta converter is that, it does not suffer the polarity reversal problem. The aim of the proposed work is to design a Zeta converter which can be used to drive the Permanent Magnet Brushless Direct Current Motor. The proposed Zeta converter is suggested to control the speed of the Permanent Magnet Brushless Direct Current Motor, according to the generated switching sequence. The proposed work is generally used for low power applications and occasionally used for medium power applications.

Abstract:

<p><span>DC-DC converters are devices which convert direct current (DC) from one voltage level to another by changing the duty cycle of the main switches in the circuits. These converters are widely used in switched mode power supplies and it is important to supply a constant output voltage, regardless of disturbances on the input voltage. In this work, the performance of three different converters such as Single-Ended Primary-Inductance Converter (SEPIC), Luo converter and ZETA converter have been analyzed. Further, the parameters values such as ripple voltage, switching losses and efficiency of the proposed three different converters were compared with each other. Also, the simulation work has been carried out using MATLAB/SIMULINK software. From the comparison of obtained results, it is observed that the ZETA converter has high significance than the SEPIC and Luo converter.</span></p>

Abstract:

This paper proposes a three-port Zeta-KY dc-dc converter which is fed with hybrid sources like photovoltaic (PV) cells and batteries. The converter proposed here is a multi-input single-output (MISO) structure which harnesses the benefits of Zeta and KY converters. The combination of these converters is highly advantageous since the Zeta converter provides lesser output voltage ripples with high gain and the KY converter topology suits well for withstanding load transients. The KY converter used in this research work is subjected to a topological change to facilitate bidirectional power flow. The bidirectional flow is essential to save the excess power in PV source in batteries during low load conditions. This novel multiport topology with bidirectional facility is first of its kind and has not been discussed earlier in the research arena. In the proposed work, two control algorithms are developed and deployed: the first one ensures the maximum power extraction from the PV and the second one maintains constant dc bus voltage and manages bidirectional power flow. MATLAB Simulink and hardware prototype of the proposed system has been realized for a 72 V dc bus and a 500 W electric vehicular drive. The simulation and experimental results reveal that the proposed system is viable for medium power electric shuttle applications. The proposed system is subjected to various test cases and it is observed that the source and load intermittencies are catered very well by the proposed three port Zeta-KY converter. The developed multiport converter is feasible for renewable energy applications.

Abstract:

In several PWM DC-DC converter topologies, the controlling switches are operated in switch mode wherever they're needed to conduct the whole load current on and off throughout every switching cycle. Recently there is an enlarged interest within the use of resonant kind DC-DC converters due to the benefits of high efficiency, small size, lightweight, reduced Electro Magnetic Interference (EMI) and low component stresses. A novel PFC (Power factor Corrected) converter feeding a PMSM drive employing a single voltage sensing element is proposed for variable speed applications. It consists of single phase supply followed by uncontrolled bridge rectifier and a Zeta DC-DC converter is employed to regulate the voltage of a DC link capacitance that is lying between the Zeta converter and a VSI (Voltage source Inverter). The voltage of a dc-link capacitor of zeta converter is controlled to realize the speed control of PMSM Drive. The zeta converter is functioning as a front end device operating in DICM (Discontinuous inductor Current Mode) and therefore employing a voltage follower. Using MATLAB/ Simulink 7.13 environment the model can be simulated to achieve a wide range of speed control.

Abstract:

This paper proposes an ac-dc converter that gives multiple outputs capable of feeding both high and low power applications. The input ac supply is converted to dc by a diode bridge rectifier, filtered and fed to a modified multiport converter (MPC). This paper focuses on the design of the modified multiport converter that has a cascaded combination of zeta and a buck converter. This is designed as a single input and multiple output converter (SIMO) structure which can operate two loads, one with a high power and other with a low power application, depending on the time instant. The need for opting a multiport converter, reduces the number of switches utilized, thereby reducing the switching losses in the circuit. The zeta in the MPC boosts the input voltage and the buck converter reduces the input voltage and is accordingly fed to the need of the load. The design of the components have been analysed through steady state. MATLAB Simulink has been used to simulate the converter circuit and the varied outputs of the zeta and buck modes are compared. A hardware prototype of the ac-dc converter has been implemented and their results have been shown.

Abstract:

<p>This paper represents a comparative study of three different types of DC-DC<br />converter that can be used for reduction of Total Harmonic Distortion (THD)<br />in stator current, back electromotive force (EMF) and torque of brush less<br />DC motor. In addition, the topologies of these converters are analysed, and<br />the THD of the output characteristics have also been studied. In this work,<br />SEPIC, Zeta and Flyback converters are considered and their outputs are fed<br />to the BLDCM with the help of universal bridge or six step inverter.<br />Moreover the THD of the output voltages are not only measured for three<br />converters but also reduced by tuning the parameters. At first these three<br />converters are modeled in MATLAB/ Simulink based simulation platform<br />and studied the performance individually and further executed with hardware<br />circuitry. Finally the output parameters from both software simulation and<br />real time hardware are compared for these three converters separately and got<br />satisfactory similar results. Again we studied the performance with these<br />converters in terms of efficiency while fed in the commutation drive circuitry<br />of BLDCM by considering minimum THD. From this comparative<br />simulation results, it has been observed that Zeta converter showed maximum<br />efficiency. Therefore, in real time hardware implementation, the<br />commutation drive circuitry of BLDCM is studied with Zeta converter. With<br />this configuration, a comparatively low THD of stator current, back EMF and<br />electromagnetic torque have been achieved in BLDCM with PID controller.</p>

Abstract:

This paper presents a systematic approach to developing turn-off snubber for an interleaving converter to smooth out switch turn-off transition. With the approach, the interleaving converter with two turn-off snubbers, which are formed by two L-C-D type snubbers, can be replaced by the one with turn-off snubber composed of a single-capacitor snubber. It can be used in the basic six interleaved converters, such as buck, boost, buck-boost, ‘cuk, zeta and sepic converters. In this research, the structure of the interleaved converter with the turn-off snubber can be conveniently simplified from the derived general configurations, reducing the complexity of circuit structure significantly. Measured results from a buck prototype converter have been verified to prove the feasibility of the derived turn-off snubber.

Abstract:

MPPT Incremental Conductance algorithm has a function to obtain maximum power points on a solar panel. This MPPT Incremental Conductance works based on the P-V curve of the solar panel. In order to obtain better power results, the MPPT Incremental Conductance system will be connected to the zeta converter. The zeta converter is a DC-DC converter that is a development of the SEPIC converter. This converter can also produce good efficiency. In this research will compare the power generated with 2 different methods, solar panels connected with zeta converter without using MPPT Incremental Conductance and solar panels connected zeta converter using MPPT Incremental Conductance. The result of the research obtained is that solar panels connected to zeta converter using MPPT Incremental Conductance can produce better power than not using MPPT Incremental Conductance.

Abstract:

<span>A dc-dc zeta converter is a switch mode dc-dc converter that can either step-up or step-down dc input voltage. In order to regulate the dc output voltage, a control subsystem needs to be deployed for the dc-dc zeta converter. This paper presents the dc-dc zeta converter control. Unlike conventional dc-dc zeta converter control which produces a controller based on the nominal value model, we propose a convex polytope model of the dc-dc zeta converter which takes into account parameter uncertainty. A linear matrix inequality (LMI) is formulated based on the linear quadratic regulator (LQR) problem to find the state-feedback controller for the convex polytope model. Simulation results are presented to compare the control performance between the conventional LQR and the proposed LMI based controller on the dc-dc zeta converter. Furthermore, the reduction technique of the convex polytope is proposed and its effect is investigated.</span>

Abstract:

The design of robust and reliable power converters is fundamental in the incorporation of novel power systems. In this paper, we perform a detailed theoretical analysis of a synchronous ZETA converter controlled via peak-current with ramp compensation. The controller is designed to guarantee a stable Period 1 orbit with low steady state error at different values of input and reference voltages. The stability of the desired Period 1 orbit of the converter is studied in terms of the Floquet multipliers of the solution. We show that the control strategy is stable over a wide range of parameters, and it only loses stability: (i) when extreme values of the duty cycle are required; and (ii) when input and reference voltages are comparable but small. We also show by means of bifurcation diagrams and Lyapunov exponents that the Period 1 orbit loses stability through a period doubling mechanism and transits to chaos when the duty cycle saturates. We finally present numerical experiments to show that the ramp compensation control is robust to a large set of perturbations.

Abstract:

A systematic method for constructing models in the complementarity framework from a bond graph is proposed. Bond graphs with and without storage elements in derivative causality are considered. The proposed method allows the study of switching systems represented by a bond graph model of fixed causality. The proposed methodology allows the complementarity framework to be exploited in different engineering areas by using bond graphs. The idea of representing a unidirectional switch with a model that is essentially the same as a diode is presented. By employing a similar representation for diodes and switches, the modeling and simulation of power switching converters are simplified and become more intuitive. Two application examples are shown. A non-inverting buck-boost converter and a zeta converter with an element in derivative causality are simulated.

A zero-voltage-switching (ZVS) Zeta converter is proposed in this paper. Two separate inductors in the conventional Zeta converter are magnetically coupled in the proposed converter. The output diode is replaced with an active switch. Also, an auxiliary inductor is utilized. The ZVS operation of both main and auxiliary switches is achieved and the switching loss is significantly reduced. Moreover, the ripple component of the output inductor current is effectively removed and the output filter stage can be simplified. To verify the feasibility and performance of the proposed converter, an experimental prototype was built and tested.

Abstract:

Renewable energy is needed as an alternative energy source. One of the implementations of renewable energy is the Solar Power Plant (PLTS). PLTS is a component that uses solar cells to convert solar energy into electrical energy. Unfortunately, the output power of this solar cell depends on the intensity of the light which causes the output power to enter the load to be unstable. Sometimes the PV power decrease because of the shading effect. From this problem a converter is needed to keep the system output voltage. The converter used in this research is the zeta converter. This Zeta converter can operate like a buck boost converter. The output of the system used is not stable. So that to stabilize it requires good control. In this paper using PI controller to control this system in order to keep the output system stable. 3. The error generated using the PI Control on the system is only 0.34%.

Abstract:

Kebutuhan konversi tegangan arus searah semakin banyak digunakan dibidang industri dalam skala besar maupun kecil. Salah satu cara untuk mengkonversi tegangan arus searah konstan ke tegangan arus searah yang dapat divariasikan adalah dengan menggunakan DC Chopper. DC chopper terdiri dari beberapa konfigurasi yang sering digunakan yaitu buck, boost, buck – boost, cuk, sepic dan zeta. DC Chopper mempunyai 2 mode operasi kerja, yaitu mode DCM (Discontinuous Conduction Mode) dan mode CCM (Continuous Conduction Mode). Banyak penelitian yang memanfaatkan kinerja DC Chopper sebagai penyedia catu daya tegangan searah. Namun dalam penelitian, karakteristik dan mode kerja konverter tidak diperhatikan dan dibahas, sehingga tidak jelas mode operasi apa yang digunakan dalam konverter. Pada Penelitian ini dibuat DC Chopper tipe zeta. Zeta converter tersebut menggunakan MOSFET sebagai saklar elektronik yang dipicu oleh rangkaian kontrol IC TL494.

Abstract:

<span lang="EN-US">This paper proposes increasing the efficiency of the autonomous Photovoltaic (PV) system by utilizing zeta converter alongside neutral point clamped multilevel inverters (NPC-MLI) based on innovative PWM scheme. The PV system acts as an input source and the relevant control of zeta converter through maximum power point tracking (MPPT) offers the maximum available power from the PV array connected to DC-link. To obtain a high voltage gain we need to exhaust the dc-link voltage as much as possible and reduce stress on the switches. For this the NPC-MLI algorithm approaches PWM technique to perform capacitive charging in parallel and discharging in series to obtain maximum voltage gain. The proposed scheme is designed and verified via detailed simulations in the MATLAB/Simulink environment. </span>

Abstract:

The usage of multilevel inverter has increased in a drastic manner for the past years. These novel inverters are useful in various mega power applications. As they are have the ability to change the output waveforms, they are having good harmonic distortions and better output results. This work proposes a novel five level asymmetrical inverter which is incorporated with the zeta converter. Comparison is made with the existing multilevel inverter with the proposed system. The simulation results give the proposed system has less THD[1] when compared to the existing inverters. The main objective is that the number of switches and capacitors are reduced which in turn reduces the loss and the cost. From the output results is has been proved that the proposed topology gives reduced loss and high quality output when compared with the conventional methods.

Abstract:

This paper aims to use the concept of energy factor and its associated concepts to analyze high-order converters, such as Cuk, Sepic and Zeta converters. The maximum variation of energy factor (MVEF) of high-order converters exhibits particular characteristic which is different from that of second order converters. To carry out the analysis based on MVEF, boundary conditions for the high-order converters should be restudied. There are new boundary conditions that are derived by analyzing the energy factor. Through the research in this paper, it can be concluded that the MVEF can reveal the amount of energy storage and impact the efficiency of high-order converters. Experimental results have confirmed that the MVEF and efficiency are correlated. MVEF can be a preferred index for DC-DC converters including high-order converters.

Abstract:

In recent times, High-Brightness Light Emitting Diodes (HB-LEDs) are developing rapidly and it is confirmed to be the future development in lighting not only because of their high efficiency and high reliability, however also because of their other exceptional features: chromatic variety, shock and vibration resistance, etc. In this paper, a Bridgeless (BL) Isolated Interleaved Zeta Converter is proposed for the purpose of reducing the diode failures or losses, the value of output ripples also gets decreased. The proposed BL isolated interleaved zeta converter operating in Discontinuous Conduction Mode (DCM) is used for controlling the brightness of LED Driver with inherent PFC at ac mains using single voltage sensor. The fuzzy logic controller (FLC) is used to adjust the Modulation Index of the voltage controller in order to improve the dynamic response of LED Lamp driver. Based on the error of converter output voltage, FLC is designed to select the optimum Modulation Index of the voltage controller. The proposed LED driver is simulated to achieve a unity power factor at ac mains for a wide range of voltage control and supply voltage fluctuations.
