Taschenbuch. Zustand: Neu. Neuware -Wireless communication is the transfer of information over a distance without the use of electrical conductors or wires. For transmitting a signal or information through a channel, it is necessary to modulate this signal or information by using a carrier signal. This procedure is called modulation. Digital modulation methods can be considered as digital-to-analog conversion and the corresponding demodulation or detection as analog-to-digital conversion. The changes in the carrier signal are chosen from a finite number of M alternative symbols (the modulation alphabet). In our work, we have analyzed MPSK and MQAM digital modulation schemes using gray mapping codes for M= 2, 4, 8, 16. We have also analyzed bit error rate as well as symbol error rate for PSK and QAM. We have compared BER vs. SNR for MPSK and MQAM in my project. We have also compared constellation diagram between the MPSK and MQAM where M= 2, 4, 8, 16. We have found different reasons for using different modulation schemes.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Various forms of energy are needed in business and social life. The conversion and transformation of electrical energy obtained from both renewable energy sources and fossil sources may be required. Direct Current to Direct Current (DC-DC) Converter circuits or Direct Current to Alternating Current (DC-AC) inverters are used in these conversions. These circuits have power switches such as MOSFET, IGBT, and GTO to provide electrical energy to the load. Signals generated by Pulse Width Modulation (PWM) techniques are used to control these power switches. Some special PWM techniques will be examined in this book. First, square PWM and Linear PWM (LPWM) are examined. Square PWM generation technique and DC-DC converter application are made and its effect on the circuit and load are examined. Secondly, the Step Sinus Pulse Width Modulation (SSPWM) technique is reviewed. SSPWM technique is produced and inverter circuit simulation applications are made on various loads. Finally, the generation of Fractional Sine Pulse Width Modulation (FSPWM) and inverter application on different loads are done.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Power electronics control systems play a pivotal role in modern electrical engineering applications, facilitating efficient energy conversion and management across various sectors such as renewable energy, electric vehicles, industrial automation, and consumer electronics. This paper provides a comprehensive introduction to power electronics control systems, covering fundamental principles, key components, and control strategies employed in the field. Beginning with an overview of power electronics devices such as rectifiers, inverters, and converters, the paper delves into the intricacies of control methodologies utilized to regulate voltage, current, and power flow. Topics including pulse-width modulation (PWM), voltage and current feedback loops, and advanced control algorithms are explored to elucidate their significance in achieving optimal performance, stability, and reliability in power electronic systems. Moreover, the paper discusses emerging trends and challenges in power electronics control, including the integration of smart grid technologies, digital control techniques, and the quest for higher efficiency and power density.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Power electronics is the engineering study of converting electrical power from one form to another. At a world-wide average rate of 12 billion kilowatts every hour of every day of every year, more than 40% of the power generated is being reprocessed or recycled through some form of power electronic systems. By 2010, it is expected this will increase up to 80%. A lot of energy is wasted during this power conversion process due to low power conversion efficiency. It is estimated that the power wasted in desktop PCs sold in one year is equivalent to seventeen 500MW power plants! It is therefore very important to improve the efficiency of these power conversion systems. It is estimated that with the widespread use of efficient and cost-effective power electronics technology, the world could see a 35% reduction in energy consumption.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Free Space Optical (FSO) Communications are able to deliver us to an age of unprecedented bandwidth, low signal attenuation, small space requirements and ultimately low cost. In FSO communications the influence of atmospheric effects can be specified by the attenuation and fluctuations of the transmitted optical power, caused by the atmospheric turbulence. This paper investigate the performance of FSO communication systems employing on-off keying (OOK) , subcarrier binary phase-shift keying (BPSK) modulation and Q-ary pulse position modulation (QPPM) in turbulence regime. The performance results are evaluated in terms of bit error rate (BER) employing subcarrier OOK, BPSK, and QPPM as modulation technique. It is found that the BER performance under BPSK modulation is better compared to other modulation techniques but in Q-ary PPM if we increase the order of Q then the performance will improve and it provide maximum 4dB improvementBooks on Demand GmbH, Überseering 33, 22297 Hamburg 80 pp. Englisch.
