Abstract:
Direct current to direct current (DC/DC) converters are required to have higher voltage gains in some applications for electric vehicles, high-voltage level charging systems and fuel cell electric vehicles. Therefore, it is greatly important to carry out research on high voltage gain DC/DC converters. To improve the efficiency of high voltage gain DC/DC converters and solve the problems of output voltage ripple and robustness, this paper proposes a double-boost DC/DC converter. Based on the small-signal model of the proposed converter, a double closed-loop controller with voltage–current feedback and input voltage feedforward is designed. The experimental results show that the maximum efficiency of the proposed converter exceeds 95%, and the output voltage ripple factor is 0.01. Compared with the traditional boost converter and multi-phase interleaved DC/DC converter, the proposed topology has certain advantages in terms of voltage gain, device stress, number of devices, and application of control algorithms.

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:
In this article, a dual-stage converter driving for a piezoelectric actuator based on flyback circuit was designed and implemented, which could be applied in a micro robot. A low-voltage direct current could be converted to a high-voltage alternating current through flyback circuit and direct current/alternating current circuit in low-power condition. In the direct current/direct current stage, the charging and discharging process was realized to generate a high voltage bias from a low voltage directly supplied by battery. Then, the high voltage was converted into alternating waveform by an energy recovery circuit in direct current/alternating current stage. Experiments were conducted to verify the ability of the proposed converter to drive a 100-V-input piezoelectric bimorph actuator using a prototype 108 mg (excluding printed circuit board mass), 169 (13 × 13) mm2, and 500-mW converter. According to the experimental results, this converter could be used for driving piezoelectric actuator applied in micro robot.

Abstract:
In low power energy storage systems, to match the voltage levels of the low-voltage battery side and high-voltage direct current (DC) bus, a high voltage gain converter with bidirectional operation is required. In this system, the cost effectiveness of the design is a critical factor; therefore, the system should be designed using a small number of components. This paper proposes a set of bidirectional converters with high voltage gain range based on the integration of the boost converter with a Ćuk converter, single ended primary inductor converter (Sepic), and buck-boost converter. The proposed converters consist of a small number of components with a high voltage gain ratio. Detailed comparisons are made with respect to the operating mode, number of components, voltage, and current ripple and efficiency. The efficiency of proposed converters are higher than the conventional converters in entire power range, and 6% higher efficiency can be achieved in large duty cycle by calculating loss analysis. To verify performances of the proposed converters, three 200-W prototypes of the converters are developed under the same experimental conditions. The results revealed that converter I exhibits the highest efficiency in the boost mode (92%) and buck mode (92.2%). The experimental results are shown to verify the feasibility and performances of the set of converters.

ENGLISH ABSTRACT: The development of fast and efficient processors, programmable devices and high power semiconductors has led to the increased use of semiconductors directly in the power supply path in order to achieve strict power quality standards. New and advanced algorithms are used in the process and calculated on-line to bring about the required fast response to voltage variations. Losses in high voltage semiconductors increase with increased operating frequencies. A balance between semiconductor power losses and power quality is achieved through control of power semiconductor switching frequencies. A predictive control algorithm to achieve high power quality and limit the power losses in the high power semiconductor switches through switching frequency control is discussed for a tap switched voltage regulator. The quality of power, voltage regulator topology and the control algorithm are discussed. Simulation results of output voltage and current are shown when the control algorithm is used to control the regulator. These results are verified by practical measurements on a synchronous buck converter.

Abstract:
The objective of the research is to develop a cost-effective high-power bi-directional dc/dc converter with low total-device ratings, reduced system parasitic effects, and a wide input/output range. Additional objectives of the research are to develop a small-signal model and control methods, and to present performance characterizations. Device stresses in the proposed topology are controlled to maintain minimal levels by varying the duty ratio and phase-shift angle between the primary and the secondary bridges, which results in a low total-device rating, when compared to conventional bi-directional dc/dc topologies. In the proposed topology, soft switching, which reduces power loss, can be realized under specific operating conditions. When the condition that causes minimal device stress is satisfied, zero-voltage switching (ZVS) can be obtained. In the research, ZVS capability is explored for a wide range of voltage conditions as well as for the minimal device-stress condition. The performance characterization includes verifying the soft-switching regions and power-loss estimation. Another part of the thesis is the controller design of the converter. Small-signal models and feedback controllers are developed, and the controllers are experimentally validated. Because in the isolated high-frequency converters, transformer saturation is an important issue, a method to prevent transformer saturation is proposed and experimentally validated.

Abstract:
The programmability property of floating-gate transistors is exploited in this work to compensate for mismatch and device parameter variations in various high performance analog circuits. A careful look is taken at the characteristics and behavior of floating-gate transistors; issues such as programming, precision, accuracy, and charge retention are addressed. An alternate approach to reduce the offset voltage of the amplifier is presented. The proposed approach uses floating-gate transistors as programmable current sources that provide offset compensation while being a part of the amplifier of interest during normal operation. This results in an offset voltage cancelation that is independent of other amplifier parameters and does not dissipate additional power. Two compact programmable architectures that implement a voltage reference based on the charge difference between two floating-gate transistors are introduced. The references exhibit a low temperature coefficient (TC) as all the transistors temperature dependencies are canceled. Programming the charge on the floating-gate transistors provides the flexibility of an arbitrary accurate voltage reference with a single design and allows for a high initial accuracy of the reference. Also, this work presents a novel programmable temperature compensated current reference. The proposed circuit achieves a first order temperature compensation by canceling the negative TC of an on-chip poly resistor with the positive TC of a MOS transistor operating in the ohmic region. Programmability of the ohmic resistor enables optimal temperature compensation while programmability of the reference voltage allows for an accurate current reference for a wide range of values. Finally, this work combines the already established DAC design techniques with floating-gate circuits to obtain a high precision converter. This approach enables higher accuracy along with a substantial decrease of the die size.

Abstract:

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB.

The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing. It is also needed for the receivers to have low power consumption since they are close to the load, which is sensitive to heat.

Different amplifier architectures were investigated to find a suitable circuit for the given prerequisites. In this report the advantages and disadvantages of voltage and current feedback are discussed.

The conclusions of this work are that in a system with an amplifier as a receiver with differential transmission lines, a single operational amplifier cannot be used. An input stage is needed to isolate the feedback net from the inputs of the operational amplifier. When fast rise time and large output swing are wanted the best amplifier architecture is current feedback amplifiers. A current feedback amplifier in CMOS with the required high voltages and slew rate is hard to realize without very high power consumption.

Abstract:
The research work described in this thesis is concerned with the analysis and design of low distortion voltage-to-current (V-I) converter bipolar junction transistor circuits. In this thesis, various voltage-to-current converter circuits published in the past have been reviewed by the author in order to understand the different techniques employed to improve the linear operating range, total harmonic distortion and transconductance. Throughout this research, the emphasis has been to improve the above mentioned parameters. All the V-I converter circuits reported have been simulated using PSpice and the results compared with the values obtained by theoretical analysis. The majority of the results of this work have been reported by the author; see Chapter 10 at the end of this thesis where all 5 publications by the author can be found in full. It was necessary to obtain precise values for certain parameters, in particular, transition frequency (fT), Early voltage (VA) and current gain (P) of the transistor to facilitate the design process. This was done using an extensive set of simulations for the transistor operating at different collector current levels. A commonly encountered requirement of the V-I circuits is an accurate non-integer ratio of current biasing. Several published such biasing schemes were studied and three new designs were conceived and evaluated. In the next part of the work several V-I converter circuits were reviewed to understand the various existing techniques and their limitations. These can be conveniently classified into three main classes of technique, namely (i) boosted-gm (ii) cross-coupled, and (iii) multi-tanh. Of these, the boosted-gm technique showed the most promise for further exploitation and development. New circuits were then developed using the boosted-gm technique with different types of feedback, classified as collector-base feedback, collector-emitter feedback and global feedback. In terms of the preferred circuit performance, these were assessed by an arbitrary but convenient, figure-of-merit (FOM) which is defined as (THDRxBW)/PD where THDR, in dB is the total harmonic distortion .reduction, BW is the 3dB bandwidth and PD is the power dissipation. On this basis, the best value of FOM (2421.24 dBMHz/mW) was achieved with the circuit called Type 2B in this thesis, which is based on collector-emitter feedback.

Abstract:
Frequency reference oscillator is a critical component of modern radio transceivers. Currently, most reference oscillators are based on low-frequency quartz crystals that are inherently bulky and incompatible with standard micro-fabrication processes. Moreover, their frequency limitation (<200MHz) requires large up-conversion ratio in multigigahertz frequency synthesizers, which in turn, degrades the phase-noise. Recent advances in MEMS technology have made realization of high-frequency on-chip low phase-noise MEMS oscillators possible. Although significant research has been directed toward replacing quartz crystal oscillators with integrated micromechanical oscillators, their phase-noise performance is not well modeled. In addition, little attention has been paid to developing electronic frequency tuning techniques to compensate for temperature/process variation and improve the absolute frequency accuracy. The objective of this dissertation was to realize high-frequency temperature-compensated high-frequency (>100MHz) micromechanical oscillators and study their phase-noise performance. To this end, low-power low-noise CMOS transimpedance amplifiers (TIA) that employ novel gain and bandwidth enhancement techniques are interfaced with high frequency (>100MHz) micromechanical resonators. The oscillation frequency is varied by a tuning network that uses frequency tuning enhancement techniques to increase the tuning range with minimal effect on the phase-noise performance. Taking advantage of extended frequency tuning range, and on-chip temperature-compensation circuitry is embedded with the sustaining circuitry to electronically temperature-compensate the oscillator. Finally, detailed study of the phase-noise in micromechanical oscillators is performed and analytical phase-noise models are derived.

Abstract:
Hand axes, language, and computers are tools that increase our ability to deal with the world. Computing is a cognitive tool and comes in several kinds: digital, analog, and brain-like. An analog telephone connects two telephones with a wire. Talking causes a current to flow on the wire. In a digital telephone the voltage is converted into groups of ones or zeros and sent at high speed from one telephone to the other. An analog telephone requires one simple step. A digital telephone requires several million discrete steps per second. Digital telephones work because the hardware has gotten much faster. Yet brains constructed of slow devices and using a few watts of power are competitive for many cognitive tasks. The important question is not why machines are becoming so smart but why humans are still so good. Artificial intelligence is missing something important probably based on hardware differences.

In this article, an interval type-2 fuzzy logic controller (IT2FLC) is used as a Maximum Power Point Tracker (MPPT) to supply a large scale interconnected grid. The IT2FLC has the advantage of being able to regulate the MPP in case of severe variations of the weather conditions. A photovoltaic array is connected to AC grid via a DC-DC boost converter and a three-phase three-level Voltage Source Converter (VSC). The duty cycle of the boost converter is switched by the IT2FLC. A three phase VSC converts the VDC link voltage to AC and keeps unity power factor. The VSC control system uses two control loops: an external control loop which regulates DC link voltage to alternative current and an internal control loop which regulates the active and the reactive grid currents. Vd and Vq voltage outputs of the current controller are converted to three modulating signals used by the PWM Generator.

Abstract:
Power converters assume a significant part in fuel cell power generation systems and solar power conversion systems which are an alternative to fossil fuel production systems. There is therefore a demand for high quality power conditioning used in PEMFC systems and photovoltaic panels. This chapter proposes a hybrid electric power (FC/PV) production strategy with the use of converter topology as the power interface and also introduces a three-level inverter topology for different operating levels. The converter increases the input voltage to the rated voltage and turns into a DC bus; the multi-level inverter converts the voltage to AC and supplies AC loads. This chapter develops a hybrid electric power generation strategy, which can produce output with positive and zero sequences. Integrating the three-stage inverter into the hybrid renewable energy (FC/PV) production system allows for near sinusoidal current with low THD. The topology of hybrid energy production using the multi-level converter is tested on Matlab.

Abstract:
This chapter presents a three-cell flying capacitor converter photovoltaic (PV) system. This system consists of a DC-DC boost power converter connected in series with a multicell inverter. The perturb and observe MPPT technique has been used to extract the maximum power from the solar panel and generate the duty signal to control the switch of the DC-DC converter. The three-cell flying capacitor inverter ensures the conversion of the output voltage of the boost chopper to the alternative voltage. This topology is made up of hybrid association of commutation cells, which makes it possible to share the voltage constraint on several switches. A closed loop control based on PWM has been proposed to control the capacitor voltages of the inverter. The output current is controlled using a PI regulator. The aim of the proposed three cell inverter is to produce an approximate sinusoidal output current with a very low THD. The simulation results assess the effectiveness of the control.

Abstract:
This chapter displays a control strategy for a photovoltaic system (PV) linked to the network with two phases of a PWM converter, where the first phase is a DC-DC converter linked among the photovoltaic source and the DC-AC converter. The second phase is a DC-AC converter linked to the grid. The maximum power point (MPP) is tracked by DC-DC converter, which increases the DC bus voltage. The P&O (perturbation and observation) technique is utilized as a direct current (DC-DC) converter controller to make the PV arrays work at greatest value of power under changing weather conditions. The DC-AC converter transfers the maximum power extracted from the PV cell into the grid. To improve the energy quality produced by the photovoltaic field other than the performance of the pulse width modulation (PWM) inverter, direct power control (DPC) is used to achieve these improvements. The simulation results showed a good performance of the suggested controller. Decoupled power control is achieved successfully, and a good power quality with low harmonic distortion rate (THD) is obtained.

In this chapter a multi objective optimal power flow (OPF) is obtained by using latest Metaheuristic optimization techniques BAT search algorithm (BAT), cuckoo search algorithm (CSA) and firefly algorithm (FA) with Unified power flow controller (UPFC). UPFC is a voltage source converter type Flexible Alternating Current Transmission System (FACTS) device. It is able to control the voltage magnitudes, voltage angles and line impedances individually or simultaneously. To enhance the power system performance, the optimal power flow has been incorporated UPFC along with BAT algorithm, cuckoo search algorithm and firefly algorithm based multi objective function comprising of two objectives those are total real power loss and the fuel cost of total real power generation. The BAT algorithm, cuckoo search algorithm and firefly algorithm based OPF has been examined and tested on a 5 bus test system and modified IEEE 30 bus system without and with UPFC. The results obtained with BAT algorithm, cuckoo search algorithm and firefly algorithms are compared with Differential Evaluation (DE).

Abstract:
In the current world due to scarcity of fossil fuel, an alternative energy is required. And now thanks to shortage of gasoline in future and its dangerous impact on the environment, and its necessary to develop an alternate power to give solution for insufficient energy source. Electric motors are creating noise but we want very smooth noise-less operation and have more efficiency as compared to the traditional Engines. Wind generation is smooth and sustainable that has to be absolutely utilized by the car industry. Solar electricity is harvested by PVarrays, the terminal voltage of Photovoltaic arrays switched through a DC/DC converter to buck boost converter. Then, we are going to hybrid those energy and use it to run the vehicle. we increased the efficiency by way of using 80% on direct usage and 20% for battery charging.

Abstract:
In the recent past there has been a significant increase in the research on vibration-based energy harvesting. Wherever mechanical movement exists, a lot of heat and vibration energy is wasted which could be used and converted as a supplement to the energy requirements. Towards this objective this project aims to provide a general theory that can be used for generating electricity from vibrating as well as heat body and store the acquired energy using advanced component called the super capacitor. A combination of Cantilever beam and MMA sensor is used for the sensing vibratory motion and the Peltier sensor is used for sensing the temperature of the source. The output obtained from the former source is converted into voltage using MMA technology and the latter is converted directly into the same. Boosted voltage is stored effectively with the help of super capacitor in primary storage device. The acquired voltage from the battery is 12V with respect to this project. For the AC load, the current produced are 300mA. The output would change with respect to the vibrating and the temperature sources like generators or automotive engines

Abstract:
Currently, to evaluate the dynamic characteristics of objects, quite a large number of devices are used in the form of chronographs, which consist of various optical, thermal and laser sensors. Among the problems of these devices, the following can be distinguished: the lack of recording of the received data; the inaccessibility of taking into account the trajectory of the object flying in the sensor area, as well as taking into consideration the trajectory of the object during the approach to the device frame. The signal received from the infrared sensors is recorded in a separate document in txt format, in the form of a table. When you turn to the document, data is read from the current position of the input data stream in the specified list by an argument in accordance with the given condition. As a result of reading the data, it forms an array that includes N number of columns. The array is constructed in a such way that the first column includes time values, and columns 2...N- the value of voltage . The algorithm uses cycles that perform the function of deleting array rows where there is a fact of exceeding the threshold value in more than two columns, as well as rows where the threshold level was not exceeded. The modified array is converted into two new arrays, each of which includes data from different sensor frames. An array with the coordinates of the centers of the sensor operation zones was created to apply the Pythagorean theorem in three-dimensional space, which is necessary for calculating the exact distance between the zones. The time is determined by the difference in the response of the first and second sensor frames. Knowing the path and time, we are able to calculate the exact speed of the object. For visualization, the oscillograms of each sensor channel were displayed, and a chronograph model was created. The chronograph model highlights in purple the area where the threshold has been exceeded.
