Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (postgraduate) from the year 2013 in the subject Engineering - Geotechnology, grade: Master, Hohai University (College of Energy and Electrical Engineering), course: Automation, language: English, abstract: This paper presents the compositions observing system and applications of AWS and PGMIS which are widely inaugurated in meteorological system respectively. The brief discussion is done on technical levels and control aspects of new technology for Automatic weather station and Power Grid Meteorological Information System. Controlled by electronics devices or computer, the automatic weather station automatically observes weather and collects and transmits data. AWS is usually composed of sensor, transmitter, data processing device, data transmitting device and power supply. The transmitter converts weather parameters sensed by sensor into electric signal then; data processing device will process these electrical signals and convert them into corresponding meteorological elements. Power Grid Meteorological Information System (PGMIS) refers to the meteorological information comprehensive platform of Power Grid applied in power grid corporations at all levels, which is also a professional application system in combination of meteorological information and production and operation of power grid. The system mainly provides timely and comprehensive meteorological information related to operation of power grid to realize monitoring, tracing, forecasting and warning of disastrous weather, and offers aid decision for load forecasting, economical dispatching and accident prediction of power grid.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Bachelor Thesis from the year 2013 in the subject Electrotechnology, grade: Bachelor, Harbin Engineering University (College of Automation), course: Electronics, language: English, abstract: In recent years, with the development of power electronic devices control theory and the increasing demand of high-quality power supply, power electronics technology has aroused widely attention from scholars. DC-DC power converters are employed in a variety of applications, including power supplies for personal computers, office equipment; spacecraft power systems, laptop, Cell phones, and telecommunications equipment, as well as dc motor drives.In this project a detailed study of zero current switching buck converters is done and also practically implemented in hardware. In addition a mathematical analysis of switching loss occurring in MOSFET's is also presented and a short study of zero voltage switching is also appended. During the hardware implementation the Ton, Toff and operating frequency were found out and thoroughly tuned through the IC555 circuit and various waveforms across inductors, capacitors, load resistor and test points were noted down.In this thesis, the Buck type circuit structure and working principle are analyzed and a DC-DC buck converter is designed. The designed converter uses ZCS scheme and realized the function that the power form is converted from 12V DC voltages to 5 V DC voltages. The output voltage can be adjusted according to the output resistor. The output voltage is stable and the performance of the designed converter is ensured. Simulation study was carried out and effectiveness of the designed converter is verified by simulation results. Finlay design is implemented in hardware and PCB layout as well.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2014 in the subject Electrotechnology, grade: Master degree, Hohai University (College of Energy and Electrical Engineering), course: Power Electronics, language: English, abstract: This study employs a buck ZCS (PWM) converter and develops a novel soft-switching approach for charger batteries. This thesis presents technique for battery charger to achieve efficient performance in charging shaping, minimum low switching losses and reduction in circuit volume. The operation of circuit charger is switched with the operation of zero-current-switching, resonant components and appends the topology of dc-dc buck. The proposed novel dc-dc battery charger has advantages with the simplicity, low cost, high efficiency and the behavior of easy control under the ZCS condition accordingly reducing the switching losses. The detailed study of operating principle and circuit design consideration is performed. A short survey of battery charging system, capacity demand & its topological is also presented. In order to compute LC resonant pair values in conventional converter, the method of characteristic curve is used and electric function equations are derived from the prototype configuration. The efficient performance of charging shaping is confirmed through the practical examines and verification of the results is revealed by the MATLAB simulation. The efficiency is ensured about 89% which is substantially considered being satisfactory performance as achieved in this paper. The proposed novel ZCS buck topology thus provides a reliable solution for future battery charger applications.
