Abstract:

This thesis focuses on the development of a novel Direct Torque Control (DTC) scheme for permanent magnet (PM) synchronous motors (surface and interior types) in the constant torque region with the help of cost-effective hall-effect sensors. This method requires no DC-link sensing, which is a mandatory matter in the conventional DTC drives, therefore it reduces the cost of a conventional DTC of a permanent magnet (PM) synchronous motor and also removes common problems including; resistance change effect, low speed and integration drift. Conventional DTC drives require at least one DC-link volt

Abstract:

This thesis investigates temperature distribution and hence heat dissipation of buried power cables. Heat dissipation analysis of a simple practical application and the parameters that affect the heat dissipation are discussed. In analyzing temperature distribution in the surrounding medium , a computer program is developed which is based on gauss-seidel iteration technique. This method is applied to a sample test system and heat dissipation curves for several parameters are obtained. Also, current carrying capacities of various types of cables are determined using dissipated heat values.

A new thermal analysis technique was developed and tested. It makes use of the improvements in heat transfer characteristics associated with recent advances in heat pipe technology. Heat is extracted from a liquid sample of a melt taken in-situ from within a vessel or furnace. The rate of heat extraction is such as to cause the sample to solidify. The technique was tested both in the laboratory and on an industrial scale (Grenville Castings, Perth, Ontario). Aluminum alloys including 356, 319, Al-xSi, Al-Si-Cu-xMg, and 6063 were subjected to various melt treatments and were used to carry out t

Over time the level of inoculant will decrease due to fading and this needs to be compensated bymore additions of inoculant.

Longer stops in production will result in the previous oven not being representable and more inoculant should be added. A method to establish the inoculation level of the base iron in the oven would make it easier to control the process.

Thus, it is essential to have an idea about regenerator parameters and their effects on the system.

In the past decades, a great variety of model fitting and model free (isoconversional) methods have been developed for extracting kinetic parameters for solid state reactions from thermally stimulated experimental data (TGA, DSC, DTA etc.). However, these methods have met with significant controversies about their methodologies. Firstly, model-fitting methods have been strongly criticized because almost any reaction mechanism can be used to fit the experimental data satisfactorily with drastic variations of the kinetic parameters, and no good criterion exists to tell which mechanism is the bes

Should bone tissue surrounding implants like fixation pins die and begin to break-down, the stability of said implants becomes at risk for failure.

Spacecraft are subject to different environments while on orbit around the Earth and beyond. One of the most critical of these environments that must be counteracted is the thermal environment. Each spacecraft has an operating temperature that is specified in the mission requirements. The requirement stems from internal component operating temperatures that are critical to mission success. Prior to placing the spacecraft in orbit, engineers must be sure that the spacecraft will survive or risk losing the mission entirely. The primary way to mitigate this risk is to use a thermal vacuum chamber

The method proposed by this thesis is rearrange the input signal increasingly and subtract in order to acquire duty ratios. Therefore, no matter how many phases the system is, it is a quick way to find the relative space vectors and duty ratio. It has to be notified that the signal must be operated in linear mode.

碩士<br>國立臺灣大學<br>工程科學及海洋工程學研究所<br>106<br>Power electronic components are an important foundation of power electronic devices. In the early days, MOSFET power components dominated the power electronics industry by Silicon (Si) materials. In recent years, environmental awareness and the market are paying more and more attention to power-related high-power semiconductor components, making wide-bandgap (WBG) components get more and more attention, and let high-efficiency drive technology also have significant development. In this paper, wide-bandgap Silicon Carbide (SiC)-based power devices were us

Abstract:

碩士<br>國立雲林科技大學<br>機械工程技術研究所<br>86<br>The research describes how Finite Element Method(FEM) is used to simulate the temperature distribution of the electronic package under various environment condition. The thermal stresses due to material mismatch between different components of the package are also disscussed. The thermal model is built by FEM. The effects of various air speed on the thermal resistance of the package is studied too. Furthermore, Taguchi method is applied to find out the best combination of various geometric parameters to get the optimum thermal performance of the package.
