Abstract:
To enhance the progress of control of switching converters, IP blocks should be identified and be made available. These power technologies can be readily implemented and the pace of progress be enhanced. This article discusses the implementation of bi-lateral switches. From the example presented, it will be clear that control of the switches is a combination of fixed commutation techniques and variable intelligent control.

Abstract:
The main aim of this thesis is to develop a solar energy system for domestic utilities, using a bi-directional DC-DC boost converter with a battery storage system in it. Topologies of the converters employed in the existing system are not efficient, especially in high power applications because of complicated structures with many power devices. In order to step up the DC voltage of the solar panel to a value suitable for AC power conversion, the DC-DC converter topologies has used either multiple stages of voltage amplification or complicated structures with many power devices as the voltage g

Modern power distribution systems (PDS) utilize multiple converters, making power flow undergo several conversions between source and the load. Use of high frequency AC (HFAC) in PDSs eliminates a few stages of converters in addition to the smaller sized capacitors and inductors being used; making the converters much lighter in weight offering a variety of solutions for the weight critical applications such as spacecraft, aircraft and electric vehicle onboard PDSs.

Information Systems (IS) is the use of Information Technology (IT). Business Intelligence (BI) is a specific type of IS. A BI system is an information system that uses tools to produce and deliver information. BI has become very important in the recent era as the organizational environments are getting more complex and changing faster than ever before. Research on BI uses in academia has been somewhat limited so far. Most decisions in a university are made based on large amounts of data from internal and external sources. So, a BI tool is necessary there in operational and strategic decision m

Abstract:
The public sector, particularly healthcare organisations are under ever increasing pressure to do more with less. This coupled with the need to keep up to the constant technological changes and ever increasing abundance of information has led to many public sector organisations adopting Business Intelligence (BI) in order to leverage business value and improve decision-making. However, many organisations such as the National Health Service (NHS) continue to fail in their Information Technology (IT) related initiatives. While the rise of BI and its growing influence in organisations has attract

碩士<br>國立中正大學<br>電機工程研究所<br>99<br>The objective of this thesis is to analyze the power dissipation in bi-directional inverter system. The conduction voltage drop, equivalent series resistance and switching characteristics of the main constituted components are taken into account in the analysis process. By introducing the proposed control schemes and inductance variation corresponding to different current level, the general expressions of power losses are obtained. First, detailed power dissipation of the constituted circuit components are derived. According to the system configuration and the

Atualmente, é cada vez mais evidente e visível a quantidade de dados, que crescem a um ritmo exponencial dentro das organizações e, como tal, existe a necessidade de implementação de ferramentas de Business Intelligence (BI), capazes de fazerem o seu tratamento e posterior extração de informação e conhecimento, que permitam facilitar e dar suporte ao processo de tomada de decisão. De forma complementar, surge o Business Analytics, que, aliado ao BI se traduz numa reforçada capacidade de análise e criação de valor para o negócio, que neste caso em concreto, se irá refletir na exploração da com

碩士<br>國立臺灣科技大學<br>電機工程系<br>94<br>This thesis presents the design and implementation of a digital signal processor based bi-directional dc-dc power converter for battery charge and discharge. When power converters operate at boost mode, the low-voltage side battery will discharge and provide power for dc-link; while at buck mode, the high-voltage side dc-link will charge the battery. The output voltage can be steady with voltage and current feedback control. The high-frequency transformer which uses two windings in parallel with power converter, together with the use of interleave control will

If conventional converter input frequency and output frequency are not the same. You must use the AC-DC and DC-AC two-stage power converter to achieve frequency conversion function. If you can use a single-stage power converter and provide two different frequency AC power at the same time, it will improve the flexibility of application for power converter.
