Abstract:
Abstract This paper presents a dual inductor-fed boost converter with an auxiliary transformer and voltage doubler for sustainable energy power converters. The new topology integrates a two-phase boost converter and a dual inductor-fed boost converter. The energy stored and transferred by both inductors can attain a wide input-voltage and load range which uses a constant switching frequency, by controlling the time duration of the simultaneous conduction of the two switches. Among other current-fed type boost converters the presented topology is attractive due to the high voltage conversion ratio, less stress on the components and less switch conduction loss. To verify the feasibility of this topology, the principles of operation, theoretical analysis, and experimental waveforms are presented for a 1 kW prototype.

Abstract:
In this paper, a new zero voltage transition (ZVT) resonant boost converter is proposed. A typical boost converter generates switching losses at turning on and turning off, and these losses cause a reduction in the efficiency of the whole system. This proposed ZVT resonant boost converter utilizes a soft switching method, using an auxiliary circuit with a resonant inductor, capacitor, and two auxiliary switches. Therefore, it can reduce switching losses more so than the conventional hard switching converter. Also, the conduction period of the resonant inductor current is reduced by using a modified circuit. An experiment is conducted with the converter, which steps up the voltage from 200 V to 380 V and its switching frequency and output power are 30 kHz and 4 kW, respectively. It is confirmed that the experimental results and simulation results are the same and the validity of this proposed converter is verified. The conventional converter and proposed converter are analyzed by comparing the experimental results of two converters under the same conditions. It is confirmed that all switches can achieve soft switching and the proposed converter improves on the conventional converter by measuring the efficiency of two converters.

Abstract:
This paper proposes an interleaved high step-up converter with different soft-switching snubbers for PV energy conversion applications. For the high step-up converter, interleaved and coupled-inductor technologies are used to reduce output ripple current and increase output power level. Simultaneously, two types of snubbers, a single-capacitor snubber and boost type snubber, are introduced separately into the discussed converters for comparing their performances of conversion efficiency and switching losses. For drawing maximum power from the PV arrays, a perturbation-and-observation method realized with the microcontroller is adopted to achieve maximum power point tracking (MPPT) algorithm and power regulating scheme. Finally, two prototypes of the interleaved coupled-inductor boost converter with a single-capacitor snubber and with boost type snubber are implemented, respectively. The experimental results obtained are used to verify and compare the performances and feasibilities of the discussed converters with different snubbers in PV conversion applications. The experimental results show that the proposed system is suitable for PV energy conversion applications when the duty ratios of switches of the converter are less than 0.5.

Abstract:
Renewable Energy Sources (RES) including full cells, wind turbines, and photovoltaic panels, widely are spreading. Among all the renewable energy sources, solar power generation system tops the list. The first choice is the boost converter when the voltage step-up is the issue. But the most important subject is applying an efficient structure with high gain, cheap and quick controller circuit. Our proposed cascaded boost converter is one of such converters which consists of several cheap components such as diode, inductor, capacitor and power switch, which has same switching frequency and phase shift in comparison with conventional boost converters. In comparison with the classic cascaded boost converter, the voltage gain for the proposed structure is very high and by forming a preamplifier layer, for a duty cycle of 80 % by adding only two diodes, one inductor, and one capacitor for the second block, voltage gain is increased by 5 times compared to the classic boost converter. The proposed method provides the increased output voltage along with the duty cycle. The projected strategy has been verified with the help of Matlab/Simulink. Also, a hardware implementation of the proposed converter has been done around 200 W by applying a Jiangyin HR-200W-24V type solar panel.

Abstract:
A comparison is made in this paper between three high voltage gain converters. The first one is a boost converter with an additional level including a coupling inductor for increasing the voltage gain. The second is a converter that is capable to be extended to N parallel converter and the third one uses a clamp circuit to increase gain with a coupled inductor. Three converters are compared in voltage and current peak value and utilization coefficient of active switch and output diode, their ZVS and ZCS condition in the ON and OFF time and voltage gain. Finally the first converter circuit is simulated in PSpice with the two other converters input voltages and the results are compared.

Abstract:
<span>This paper presents the design and operation of three-stage buck-boost converter with high gain soft switching using closed loop proportional integral (PI) controller. The proposed converter is designed by arranging three identical buck-boost converters working in parallel. The converter units are connected to each other by an inductor as a bridge. This inductor plays a vital role in soft switching operation of converter by maintaining the voltage applied to switches at zero voltage at switching intervals, i.e., the zero-voltage switching (ZVS). The closed-loop system is designed by PI controller, and it maintains the output constant irrespective of changes in input, and the system becomes stable. The proposed converter is efficient in reducing switching losses, leading to improved converter efficiency. Due to parallel operation of three identical converters, the output voltage and input current contain fewer ripples than those of a single converter with same specifications. Proposed converter is more economical and reliable with simpler structure as it utilizes only two inductors as extra elements. The design and analysis of proposed circuit has been carried out in MATLAB Simulink by operating the circuit in various modes.</span>

Abstract:
This thesis examines converter topologies suitable for Module Integrated Converters (MICs) in grid interactive photovoltaic (PV) systems, and makes a contribution to the development of the MIC topologies based on the two-inductor boost converter, which has received less research interest than other well known converters. The thesis provides a detailed analysis of the resonant two-inductor boost converter in the MIC implementations with intermediate constant DC links. Under variable frequency control, this converter is able to operate with a variable DC gain while maintaining the resonant condition. A similar study is also provided for the resonant two-inductor boost converter with the voltage clamp, which aims to increase the output voltage range while reducing the switch voltage stress. An operating point with minimized power loss can be also established under the fixed load condition. Both the hard-switched and the soft-switched current fed two-inductor boost converters are developed for the MIC implementations with unfolding stages. Nondissipative snubbers and a resonant transition gate drive circuit are respectively employed in the two converters to minimize the power loss. The simulation study of a frequency-changer-based two-inductor boost converter is also provided. This converter features a small non-polarised capacitor in a second phase output to provide the power balance in single phase inverter applications. Four magnetic integration solutions for the two-inductor boost converter have also been presented and they are promising in reducing the converter size and power loss.

A lot of electronic products require more than one power supply for the system. It will inevitably need a lot of power converter to provide stable voltage and it will occupy a larger silicon area and high power consumption. Therefore, design a high efficient converter with small size is a great challenge。 In this paper, we propose two kinds of converters are using pulse width modulation technology (PWM). One is the single-inductor dual-output (Single-Inductor dual-output, SIDO) buck converter, where the first output voltage is 3.3V and the second output voltage is 2.5V. The PWM frequency operates on 250KHz that can play a maximum output loading current of 1A when the another output is 250mA. The output voltage can be stable at 3.3V and 2.5V in practical tests when the input voltage is 4~5V. The maximum efficiency can reach 94%. The other is single-inductor dual-output (single-inductor dual-output, SIDO) DC - DC buck-boost or boost-boost power converter. For buck-boost converter, the first is the boost output, where the output voltage is 6V; the second is buck converter, where the output voltage is 3.3V. The PWM frequency operates at the 125KHz, which the maximum output loading current is about 150mA.When he input voltage is 5.3V, the output loading current supports 66mA and 100mA for 6V and 3.3V respectively. The highest efficiency can reach 89%. Two converters using the same inductor, which can save chip area and reduce power dissipation, when compared to the traditional converter.

Two-inductor boost converter with auxiliary transformer is suitable for applications with a large difference between the input and output voltage. The converter is achieved in a wide load range with constant-frequency control by employing an auxiliary transformer that couples the current paths of the two boost inductors. Zero-Voltage-Transition techniques which combine PWM with the soft-switching characteristics make the converter can be operated at constant frequency. ZVT structure has no increase voltage and current stress. The rectifier diode also has soft-switching characteristic. Therefore, ZVT converters have the minimum conduction loss. This thesis will analyze and discuss the characteristics of the ZVT-PWM technique applied to the two-inductor boost converter.

Abstract:
DC-DC power converters are necessary to step-up the voltage or current with high conversion ratio for many applications e.g. photovoltaic and fuel cell energy conversion, uninterruptible power supply, DC microgrid, automobile, high intensity discharged lamp ballast, hybrid vehicle, etc. in order to use low voltage sources. In this project, a modified SIBC (mSIBC) is proposed with reduced voltage stress across active switches. The proposed mSIBC configuration is transformerless and simply derived by replacing one diode of the classical switched inductor structure with an active switch. As a result, mSIBC required low voltage rating active switches, as the total output voltage is shared between two active switches. Moreover, the proposed mSIBC is low in cost, provides higher efficiency and required the same number of components compared to the classical SIBC. The experimental results are presented which validated the theoretical analysis and functionality, and the efficiency of the designed converter is 97.17%. The proposed mSIBC converter provides higher voltage conversion ratio compared to classical converters e.g. boost, buck-boost, cuk, and SEPIC. The newly designed configurations will aid the intermediate power stage between the renewable sources and utility grid or high voltage DC or AC load. Since, the total output voltage is distributed among the two active switches, low voltage rating switches can be employed to design the power circuit of the proposed converter. The classical boost converter or recently proposed switched inductor based boost converter can be replaced by the proposed mSIBC converter in real-time applications such as DC microgrid, DC-DC charger, battery backup system, UPS, EV, an electric utility grid. The proposed power circuitry is cost effective, compact in size, easily diagnostic, highly efficient and reliable.
