Abstract

To obtain a suitable ohmic contact with low specific contact and sheet resistance, a thin film of Mo~1μm is deposited on n-type multi crystalline Si wafer by RF sputtering in Argon atmosphere. The ohmic characterization of Molybdenum contact was investigated by the Keithley 2361 and the sheet resistance was measured by the four point probe. Two sets of experiments were carried out to study the resulting deposition of Molybdenum thin film. In the first experiment, during the deposition process, the RF power was varied at constant 100, 200 and 300 Watts and in the second experiment RF power was kept at a constant 300W, while the Ar gas flow was varied at constant 10, 30 and 50Sccm.The specific contact resistance was not affected by varying the RF power of deposition; it remained at about 1×10^-3 Ωm² . However, the sheet resistivity reduced to 1.6×10^-5 Ωm. Although varying the RF power did not impact the resistivity of the contact by much, the XRD spectra of the samples show that there was an increase in the crystalline structure, as the RF power was increased. The best result was achieved with the lowest Ar gas flow with the specific contact resistance of 8×10^-4 Ωm² and the sheet resistivity of 3.3×10^-6 Ωm.The low Ar gas flow not only yielded the sample with the lowest specific contact and sheet resistivity, it also produced the sample with the most orderly deposited molybdenum grains; as observed with the SEM.

Abstract

This paper presents an optimal control of Permanent Magnet Linear Synchronous Motor (PMLSM) using linear quadratic regulator. The linear quadratic regulator is employed by linearization of motor model to obtain the optimal state feedback gain matrix. Optimal Control Methodology facilitates to design a control system, to meet the performance objectives with the smallest control energy i.e. the energy associated with the generation of control inputs. In pole placement techniques, Trial and Error method is adopted to find the pole location for desired performance of the system, whereas the optimal control methods directly formulate the desired performance of the control system The PMLSM drive is simulated by taking various Q and R matrices in order to eliminate the steady state error and enhance the dynamic performance of various speed profiles.

Abstract

Voltage stability is regarded as one of the important areas of power system stability studies. A power system facing disturbances is at risks of voltage instability. Prime reason for the cause of instability is the sag in reactive power at various locations due to circuit contingencies. These are classified under large disturbance voltage stability. The aim of this paper is to identify the optimal location of Thyristor Controlled Series Capacitor in an interconnected transmission power system under N-1 contingency using Cat Swarm Optimization technique.

Abstract

The use of Induction motors has increased tremendously, since the day of its invention. They are being used as actuators in various industrial processes, robotics, house appliances and other similar applications. The reason for increasing popularity day by day can be primarily attributed to its robust construction, simplicity in design and cost of effectiveness. This paper presents a methodology for implementation of a rule-based fuzzy logic controller applied to a closed loop Volts/Hz speed control of induction motor. The Induction motor is modelled using a dq axis theory. The designed Fuzzy Logic Controller's performance is weighed and is compared with that of a PI controller. The system has been simulated in MATLAB/SIMULINK and the results have been presented. The results obtained by using a conventional PI controller and the designed Fuzzy Logic Controller have been compared.

Abstract

In this paper, a new multilevel converter which consists of only the seven switches rather than the conventional multilevel converter is analyzed. The various PWM techniques were included: APODPWM, COPWM and PSPWM, to generate the respective output voltage levels. It has many main advantages of lower harmonics, reductions in installation space and cost of inverter. The performance measures like Total Harmonic Distortion (THD), VRMS (fundamental) and V_peak are evaluated for various modulation indices. This proposed multilevel converter can be analyzed and investigated through MATLAB/SIMULINK software. Finally, compared with all PWM strategies, the COPWM and PSPWM provide higher (Fundamental) RMS voltage and APOD PWM provides lower Total Harmonic Distortion (THD) .
