Capacitor Based Resonant Converter with Phase Shift Control
ISBN: 9783659265464 / Angielski / Miękka / 2014 / 88 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This project proposes operating performance of a switched capacitor based resonant converter (SCRC) using a phase-shift control method. The proposed phase shift control realizes zero voltage switching operation, and thus achieves a high conversion efficiency. A theoretical analysis shows that the SCRC can reduce its inductor volume compared with a conventional buck converter when the output voltage range is within 19%-81% of its input voltage. Experimental results verify the operating characteristics of the proposed method and show the improved conversion efficiency of more than 99%.

Economic Dispatch Using Particle Swarm Optimizer Techniques
ISBN: 9783659520617 / Angielski / Miękka / 2014 / 56 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Four modified versions of particle swarm optimizer (PSO) have been applied to the economic power dispatch with valve-point effects. In order to obtain the optimal solution, traditional PSO search a new position around the current position. The proposed strategies which explore the vicinity of particle's best position found so as far leads to a better result. In addition, to deal with the equality constraint of the economic dispatch problems, a simple mechanism is also devised that the difference of the demanded load and total generating power is evenly shared among units except the one...

Design of Boost Converter with Coupled Inductor
ISBN: 9783659229503 / Angielski / Miękka / 2014 / 116 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A novel isolated zero-voltage-transition boost converter with coupled inductors is proposed in this project to satisfy the high power, high step-up and isolated requirements. In the proposed converter, the input-parallel configuration is adopted to share the large input current and to reduce the conduction losses, while the output-series structure is employed to double the output voltage gain. Consequently, a transformer with a low turns ratio can be applied, which makes the transformer design and optimize easily. Moreover, the active clamp circuits are employed to reduce the switch voltage...

Frequency Control For Wind Mill Applications
ISBN: 9783659469350 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The wind power is a popular form of energy generation, the construction of wind farms and small wind electric generators are not universally welcomed because of the power quality issues due to which the converted energy could not be used more effectively. The frequency mismatch is one of the major crisis under the power quality issues when the renewable energy system is connected to the grid. Therefore the main objective of this project is to equalize the number of cycles per second in the grid as well as number of cycles per second in the inverter under different load conditions at various...

Shunt Active Power Filter with Unipolar PWM technique
ISBN: 9783659519574 / Angielski / Miękka / 2014 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The main objective of this project is to make the total input current drawn from the three phase ac main as sinusoidal, by compensating reactive power and low order harmonics generated by the three phase non-linear loads. The synchronous d-q-o reference frame algorithm is also been implemented to recognize and extract harmonic distortions. The outcome will be Total Harmonic Distortion free supply mains. such that the input current will be compensated.The filter is used to counter the effects of harmonics on three-phase power distribution systems and thus improve the system power quality....

Estimation of Variance Components
ISBN: 9783845429687 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Estimation of variance components in mixed linear models is an important problem in statistical inference to draw a valid and meaningful interpretation in many practical areas of research. ANOVA, Analogous to ANOVA, SS Approach, ML, REML, MML, MINQUE, MIVQUE and QLSE are some of the important methods available in literature for estimation of variance components in general mixed linear models. In this book we have introduced MTE, WQLSE and modified MIVQUE estimators and also derived their variances and also the covariance matrices. In fact we have presented the explicit computable expressions...

Secure and Anonymous Routing for Mobile Adhoc Networks
ISBN: 9783844327724 / Angielski / Miękka / 2014 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Mobile adhoc networks require stronger privacy protection due to the open nature of their media. Schemes such as AODV, ANODR, ALARM uses either one time or long term public key cryptosystems or combination of both achieving only partial anonymity and unobservability. Also, these schemes depend on public key cryptography and hence incurring high computation overhead. Our proposed technique overcomes these disadvantages by employing group signature and ID based encryption together instead of Public Key Cryptosystem. This scheme is thought to offer complete unobservability of both types. Our...

Highly Consistent and Secured Data Delivery for Mobile Ad-Hoc Networks
ISBN: 9783659143724 / Angielski / Miękka / 2014 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Mobile Ad-hoc Network is an infrastructure less and decentralized network which needs a robust dynamic routing protocol. Many routing protocols have been proposed to accommodate the needs of communications for Mobile Adhoc Network. In this project, there is problem in delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. Most existing ad hoc routing protocols are susceptible to node mobility, especially for large-scale networks. Driven by this issue, an efficient protocol was introduced. It takes advantage of the stateless property of geographic...
