A sub-millimeter scale coil is investigated as an alternative means to power electronics for small-scale robots. The AC voltage is induced by timevarying magnetic field. FEM analysis of employing magnetic field concentrators to increase the field density is carried out, concluding with their ineffectiveness to offset the occupied space. The choice of conductive versus non-conductive photoresist...

Given a graph G and a (multi-)set of pairs of vertices in it, the classical NP-hard maximum edge-disjoint-paths problem (MDP) is to connect as many of the given pairs as possible using pairwise edge-disjoint paths in G. We study a related generalization of this problem to the low bandwidth case: we have a network with xed capacities that may have to service large demands when necessary. In part...

GaAs PHEMTs are broadly used in RF power applications for wireless systems. A major concern with these devices is their gradual degradation as a result of prolonged biasing at high voltages. Previous research has identified the drain side of the device as the region that sustains most of the damage [1], but other mechanisms involving charge modulation under the gate [2] have also been reported....

Power grid vulnerability to targeted attack has been a focus of research after the robust yet fragile nature of complex systems was discovered. Various measures has been proposed to analyze the topological fragility since then. This paper focuses on providing a matrix which is able to find out critical elements within the system. A step by step method for building the matrix is shown. Various v...

In this paper, a procedure for identifying the transfer functions of Park’s dq-axis model of a synchronous generator has been developed for analyzing automotive charging systems. This application note focuses on one particular aspect of charging system design: alternator/regulator performance. This voltage regulated power system must operate satisfactorily under extreme transient conditions. Tw...

The chapter covers general issues related to power quality in Electric Arc Furnaces. The use of electric arc furnaces (EAF) for steelmaking has grown dramatically in the last decade. Of the steel made today 36% is produced by the electric arc furnace route and this share will increase to 50 by 2030. The electric arc furnaces are used for melting and refining metals, mainly iron in the steel pro...

Recent developments in photovoltaic components, small-scale combined heat and power systems and ducted wind turbines have opened up the possibility for an embedded generation approach to building design. In conjunction with demand reduction measures, embedded generation encourages a new design paradigm based on matching local supply to demand. For building simulation programs to offer effective...

Electrical power forecasting plays a vital role in power system administration and planning. Inaccurate forecasting can lead to the waste of scarce energy resources, electricity shortages, and even power grid collapses. On the other hand, accurate electricity power forecasting can enable reliable guidance for the planning of power production and the operation of a power system, which is also im...

The scope of this paper is to focus on cost effective, reliable and eco-friendly operation of power system. Power is key to economic development of any country especially fast developing countries like India. In the global environment, no country can be competitive unless, it has adequate and affordable power availability. Economic load dispatch is vital component in the operation of power syst...
