Some of the system disagreeing regarding the vocational groups with respect to future higher education and also the jobs in future. In other side it some system says that the vocation group will not lead the students to prepare for their gate exams and it does not lead them for higher education. In this field work this paper show the ways how the vocational group support for student for their higher education as well as the steps can be followed by the school management to remove the fear of the society about the vocational group. This analysis was carried out with the help of NGO Dr.A.P.J. Abdul kalam educational trust and support of the school managements. Finally, this paper helps and gives a guidance for the vocational group students. Education is a powerful light with shows the path for others: Vocational education helps to prepare students for a specific career. This type of education can take place in schools, technical schools or on-the-job training programs. Vocational education usually consists of a mix of theory and practical, hands-on experience.

This paper focuses on the behavior of Multi junction solar cell systems. The PV cells can offer better simulation results using multi junction solar cell. In a single-diode model still it require more improvements, thus multi junction solar is analyzed to get better and more accurate to produce maximum output. So Multi junction solar cell is compared with the conventional silicon PV cell to show better performance for power electronic devices. Multi junction solar cell can provide almost 3-times maximum power compared to the single solar cell. By connecting renewable energy source with the electric drives it needs advanced power electronics converter. Due to this proposed converter needed for high power and medium voltage situations. A universal bridge with filters will improves the performance of the system. A PWM technique is pursue for this converter to trigger the power devices. This converter reduces the sources, switches and increasing the level to improve the efficiency of the converter. This converter is used for high power and voltage applications. By reducing the switches power loss can be reduce in converters. MATLAB software is used to simulate the converter and FFT analysis is carried out to observe the Total harmonic distortion. This paper shows how to produce a suitable sine wave by using less number of semiconductor switches (MOSFET, MESFET, IGBT, GTO etc...).By PWM technique using MATLAB/SIMULINK software the operation and model of the proposed converter was designed by using less number of switches. The proposed circuit produces high efficiency and also less total harmonic reductions (THD) by the help of simulation.. 202 Ms.J.Suganthi Vinodhini and Dr.R.Samuel Rajesh Babu

In this world already a constant voltage constant frequency single phase and three phase AC readily available. For some applications it is needed to have variable voltage and variable frequency for this conversions need between dc and ac sources, and this conversion can be carried out by power converters. For converting AC–AC cycloconverter are widely used as a converter. The ns of alternating current drives relates with the frequency (f) and number of poles (p) present in the induction motor .It is not feasible by changing the poles of a motor under running processes, so the only one way during running condition the frequency can be varied. In the absence of direct current (DC) link with constant voltage constant frequency alternating current to variable voltage variable frequency alternating current is needed to run the electric traction applications, so the cycloconverter will make this as possible with reliable and economical. This work explains how to control the speed of single phase induction motor and single phase to single phase Cycloconverter using different frequency conversions with R Load was carried out using MATLAB / Simulink.

This paper presents a brief overview of all types of locomotives with its traction motors specifications, types of rectifiers and inverters used for conversion of power to traction motor and various types of converters used nowadays in ER's. Based on already existing information, this paper presents the overview on converters using in locomotives. It is apparent that for most electrically-fed railways, the use of modern power converters is attractive. Where the electric railways are high consumers of energy, the railway gradients are significant, and the public grids feeding the railways are weak, the use of converters would be technically desirable, if not necessary for electrification. This paper presents about the regenerative braking in locomotives and EMI problems occurring in Electric Railways.

Recent advance technology was proposed on locomotive by ABB, ALSTOM, HITACHI, etc. but still there is a disturbance in converters by converting AC/DC/AC. This proposed topology called multilevel inverter using PIC reduces the total harmonic distortion and also while triggering the gates in inverter the shot circuiting between gates in locomotives was minimized. In his work a harmonic was injected to reduce the switching looses while trigger the switches called IGBT for inverter in locomotives. The simulation for multilevel inverter using harmonic injection method was carried out using MATLAB/SIMULINK and the hardware result is shown in this work.

Three-phase induction engines are driven by voltage source inverters. This chapter investigates different multilevel converters. The speed and contortion which exists in three-phase locomotives was controlled by variable voltage, variable frequency (VVVF), and the modulation index was expanded to reduce the distortion in the yield voltage and current. In this chapter the modulation index was increased with respect to the frequency of the three-phase induction motor. In current insulated gate bipolar transistor (IGBT) trains voltage stresses exist. These are investigated and reduced using a proposed framework for WAP-7D locomotives. Simulations were done across an entire district investigating speed, torque, voltage, and braking effort in traction motors, utilizing MATLAB programming.
