The most distinct advantage of electric vehicle is its quick and precise torque generation. However, most electric vehicles developed until now have not yet utilized it. In this paper, two novel traction control techniques of electric vehicle using this advantage are proposed. One is the model following control and another is the optimal slip ratio control. The basic effectiveness of the propos...

with increase in traffic and speed railway became one of the major load on supply grid .AC-DC convertor used in locomotive of traction system draws rich harmonics content current results in poor power quality and failure or missed operation of utility causing derating of grid and affect the reliability. This paper provide framework for issue like harmonics, voltage sage ,voltage unbalance, poor...

This paper presents three power module cooling topologies that are being considered for use in electric traction drive vehicles such as a hybrid electric, plug-in hybrid electric, or electric vehicle. The impact on the fatigue life of solder joints for each cooling option is investigated along with the thermal performance. Considering solder joint reliability and thermal performance, topologies...

Due to the growing concern about global environmental problems and shrinking nonrenewable energy sources, research on electric vehicles and hybrid electric vehicles is once again attracting significant attention. Meanwhile, significant improvements in power electronics, energy storage and control technology have made electric vehicles fully feasible, preparing the state of the art for their ret...

Aim: selection of a traction motor for electric freight transport operating in the Arctic.
 Methods: To achieve this aim, main characteristics existing types DC and AC motors were considered, as well data on use one or another type modern vehicle.
 Results: A comparative analysis most common has led to 2 leaders - permanent magnet synchronous (PMSM) an induction (IM). Both are fully s...

The electric traction system used in trains is the most energy efficient traction system in the transportation sector. Moreover, it has the least NOx and CO2 emissions in comparison to other transportation systems (e.g. busses, passenger cars, airplanes, etc.). On the other hand, they are extremely expensive, mainly due to high installation and maintenance cost of the catenary system, including...
