The equivalent series inductance (ESL) of the DC link capacitor and associated bus structure connecting to the switch module has important implications for optimization of electric vehicle inverters. In many cases, additional snubber (bypass) capacitors can be eliminated for sufficiently low ESL, thus reducing cost, weight and volume. This paper presents ESL measurements for realistic capacitor...

A polarizable quantum mechanics and molecular mechanics model has been extended to account for the difference between the macroscopic electric field and the actual electric field felt by the solute molecule. This enables the calculation of effective microscopic properties which can be related to macroscopic susceptibilities directly comparable with experimental results. By separating the discre...

Bus routing is one of the most important elements of public transit system planning. This article presents a model for optimizing service headway and a bus route serving an area with a commuter (many-to-one) travel pattern. The bus route is optimized by minimizing the total system cost, including operator and user costs, while considering diagonal links in the study network. A method is develop...

The impending deregulated environment facing the electric utilities in the twenty first century is both a challenge and an opportunity for a variety of technologies and operating scenarios. Changing regulatory and economic scenarios, energy savings and environmental impacts are providing impetus to the development of an Active Distribution Networks (ADN), which is predicated to play an increasi...

Residual acoustic hearing can be preserved in the same ear following cochlear implantation with minimally traumatic surgical techniques and short-electrode arrays. The combined electric-acoustic stimulation significantly improves cochlear implant performance, particularly speech recognition in noise. The present study measures simultaneous masking by electric pulses on acoustic pure tones, or v...

Deregulation is the major trend in the electric power industry throughout the world. The main focus in deregulated system operation is to optimize the system welfare by introducing competition, mainly, among generators. The grid operator is required to know how the power offered by the generators is reaching the load; for which the power flow is to be traced along the lines. Tracing of electric...

The power dissipation associated with driving data busses can be significant, especially considering the increasing component of inter-wire capacitance. Previous work on bus encoding has focused on minimizing transitions to reduced power dissipation. In this paper, it is shown that transition reduction is not necessarily the best approach for reducing power when the effects of inter-wire capaci...

Distribution networks transport electric energy to the end user from distribution substations. Power utilities are looking for improved power delivery performance. The performance of the delivery system is measured by the power loss of the system. The increase in power loss increases the operating cost of the distribution system. This paper presents an algorithm to minimizing the power loss of ...

This paper presents the performance comparison of meta– heuristics algorithms such as DE (Differential Evolution), PSO (Particle Swarm Optimization) and GA (Genetic Algorithm for the problem of Transmission Power Loss (TPL) minimization using Flexible AC Transmission System (FACTS) devices. In addition to that a novel power flow method is proposed using Broyden – Shamanski method with Sherman –...

The greenhouse gases and air pollution generated by extensive energy use have exacerbated climate change. An electric-bus (e-bus) transportation system favors reducing pollution and carbon emissions. This study analyzed the minimization of construction costs for an all batteryswapping public e-bus transportation system. A simulation was conducted according to existing timetables and routes. Day...
