Abstract:

This thesis studies the factors that influence the optimization, and sizing, of dry bulk terminals, while looking for a model to reflect them. At the same time it provides an overview of dry bulk shipping, and its marine operations, while identifying literature linked to the sector. In the first part (Chapter 1 y 2) we study and analyze all the factors that tend to influence or affect the characteristics of a port terminal. In the second part (Chapter 3 and 4) a series of international terminals are analyzed, called "Wold Champions" and a part of the largest bulk terminals in the spanish co

碩士<br>國立臺灣海洋大學<br>航運管理學系<br>100<br>The sharp fluctuation in bulk shipping markets and freight rates highlights the difficulty in operating bulk shipping corporations. In the highly competitive global environment, the relatively small-scale of bulk shipping market in Taiwan makes the business operations much more difficult than other bulk shipping markets. Therefore, how to enhance shipping competitiveness by improving the operational performance is an important issue for bulk shipping corporations. However, seldom researches focused on this issue in the past. The evaluation of operational

The derived circuits are obtained from the integration of a dual-switch boost-type or buck-boost-type power factor corrector (PFC) into a half-bridge resonant converter. With symmetrical topology, the circuit is simple and the voltage and current stresses on the two active power switches are identical to each other. The PFC is operated at discontinuous conduction mode (DCM) to achieve unity power factor. The re

碩士<br>國立臺灣科技大學<br>電子工程系<br>101<br>The main purpose of this thesis is to study and implement an interleaved buck power factor corrector (PFC) with high-frequency operation. High-frequency operation can reduce the inductor size and the converter’s volume. The inductors for the interleaved topology are integrated into one inductor. Additionally, the traces on the PCB are treated as windings to further reduce the cost and volume. With the buck-type topology, the voltage rating for the output capacitor is lower. High switching frequency will result in higher switching loss. Therefore, GaN-based FET

When input voltage is higher than output voltage, the MPPT operates in buck mode; otherwise, it operates in boost mode. When input voltage changes between high voltage and low voltage, the mechanism of changing reference input voltage is adopted to switch the operation mode. This tracker controller uses microcontroller TMS320LF2406A, and the control algorithm is based on the perturb and observe method. In add
