The aim of this paper is to bring new contribution and new technology for locomotive especially for WAP-7. 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...

This paper presents a bidirectional inverter using artificial neuro-fuzzy interface system ANFIS. The applications of this proposed topology is to maintain a constant speed in three phase induction motor for locomotives. Nowadays power electronic inverters are popular for industrial applications to drive various AC loads. In this paper a new approach is presented to implement the ANFIS in bidirectional...
In electric traction application electrical energy used was: 1.direct current and 2.alternating current. 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...
This paper presents a new twenty seven level cascaded H-bridge multi level inverter for locomotives. This proposed multi level inverter can overcome the need for a large number of electronic switches when the number of level increased. This proposed topology increases the efficiency of the inverter by reducing the switching losses using pulse width modulation technique. Recently in Japan they developed...

In this paper, a comparative analysis of with and without injecting the harmonics in switching techniques for multilevel inverter was carried out. The multilevel inverter are said to be the power converter systems where the by controlling the power semiconductor sources properly a controlled multistep voltage waveform will generate. The first approach on multilevel inverter is carried out in Simulink...
This paper compares the open loop and closed loop system for a single phase Cyclo converter. This paper compares the characteristics like mechanical, speed and torque characteristics of the open loop and closed loop system. In this paper PWM technique is employed along with cyclo converter using IGBT which increases the performance and control of the system. Special advantage of using IGBT in this...
