Power losses of multiphase inverters
Electrical Systems for Aircraft, Railway and Ship Propulsion, 2010Multiphase drives are particularly attractive in medium and high-power applications such as railway and naval propulsion systems. In the most modern drives, a multiphase machine is driven by an IGBT inverter. This paper focuses the theoretical calculation of the power losses in multiphase inverters with an odd number of phases.

Power losses in lamellar gratings
Applied Optics, 1979Power losses in lamellar gratings per groove length are obtained by integrating the square of the tangential component of the magnetic field, obtained from the infinite conductivity solutions, along the grating profile. The groove fields for the perfectly conducting grating are generated by matching a superposition of diffracted plane waves above the ...

IEEE Transactions on Power Systems, 2020
This letter presents an analytical closed-form expression that quantifies the contributions of nodal active- and reactive-power injections to total loss in a power system operating at sinusoidal steady state. We term this as the loss divider , since it is derived by leveraging the ubiquitous current divider law.

American Sociological Review, 1973
Berle and Means show that modern organizations separate the rights inherent in property or other resources into benefit rights and usage rights. To increase benefits, natural persons in society give over usage rights, that is direct control over actions, to corporate bodies through investments or membership. In so doing, they have gained these benefits

Power Losses in Electrolytic Condensers
Transactions of the American Institute of Electrical Engineers, 1932Electrolytic condensers on a-c. circuits have higher power losses than would be expected from the leakage currents and electrolyte resistances. Likewise, losses change with the applied voltage, with temperature of the cell, with the frequency of the applied voltage, and with external circuit conditions governing current wave shape in such ways that it ...

Load Loss Coefficient and Power Loss Tracing in Power Systems
2017A definition of Load Loss Coefficient (LLC) is given in this study along with the power loss tracing algorithm. As LLC indicates the effect of load on power transmission loss, its calculation is performed based on the Bialek’s power tracing method, where gross and net flows are being considered, to determine the power loss in a system during power ...

International Journal of Mechanical Sciences, 1970
Abstract This paper examines power-producing cycles and evaluates losses incurred in such a way that the analysis applies to cycles as a whole or to individual units involved. This allows the results to be applied to any process where work and/or heat transfer is involved.

Power Losses in Induction Machines
Transactions of the American Institute of Electrical Engineers, 1934Losses in induction machines have been subjected to a detailed study by many investigators, but due to the complex nature of some of these losses, particularly several forms of load loss in induction motors, a clear understanding of their nature, has not been available.

Stochastic Power Loss Analysis of Differential Power Processing
IEEE Transactions on Power Electronics, 2022This article presents stochastic power loss analysis for differential power processing (DPP). A stochastic model is developed to analyze power loss scaling in a DPP system based on probability distributions of loads or sources. Scaling factors are introduced to describe how losses change with DPP system size and load or source power variance.

Rubber Chemistry and Technology, 1959
Abstract Rubberlike polymeric materials, particularly in the technical form when compounded with carbon black, are imperfectly elastic and the associated energy loss is of considerable practical significance. In some applications a high energy loss is of value to provide high damping, but in many cases and particularly in tires, the temperature
