this paper presents developing an analytical model for flux switching motors. the motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. this paper presents a simple model which is able to predic...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

We are starting to investigate a novel multiplexable readout method that can be applied to a large class of superconducting pair-breaking detectors. This readout method is completely different from those currently used with STJ and TES detectors, and in principle could deliver large pixel counts, high sensitivity, and Fano-limited spectral resolution. The readout is based on the fact that the k...

A numerical procedure for extracting parasitic circuit elements using a quasi-static field solver, as part of the Virtual Test Bed (VTB), is discussed. The parasitic inductance and capacitance values obtained from the model are compared to measured values from a low-inductance Power Electronic Building Block (PEBB) module, designed and constructed at Harris Semiconductor.

Abstract Typical DC-bus stabilization for low-voltage power circuits consists primarily of ceramic capacitors due to the capacity density and low equivalent series resistance (ESR) resulting in conduction losses. Particularly hard-switching hard-commutation operation, ESR high inductance (ESL) commutation path restrict damping switch node voltage overshoot introduce high-frequency ringing, redu...

Some major problems in the motor drive are overshoot or undershoot of transient response characteristics and a parameter mismatch due to magnetic saturation. This study proposed 3D inductance map combined with maximum-torque-per-ampere (MTPA) based on finite-element (FE) model considering cross-coupling saturation impact overcome this problem. The FE has high accuracy no-load back electromotive...

Electrochemical impedance spectroscopy (EIS) is a powerful tool to characterize and distinguish electrochemical, electrical, diffusive processes in an electrolysis cell. The EIS response with small (mOhm) depends on components materials of the cell, but often also electrical setup, cables, connectors, leading incorrect conclusions about performance cells. These effects are assessed via short ci...

This paper provides a high level survey of the increasing effects of on-chip inductance. These effects are classified into desirable and nondesirable effects. Among the undesirable effects of on-chip inductance are higher interconnect coupling noise and substrate coupling, challenges for accurate extraction, the required modifications of the infrastructure of CAD tools, and the inevitably slowe...
