The paper has two different objectives. The first one is to show that Ampere’s double layer method, which is equivalent to one of the Maxwell equations, leads to the integration of a simple closed form expression, thus avoiding the need to solve co

The authors have improved a circuit model of transformers by defining a conductance whose losses will be close to the iron losses under any circumstance. Connecting a constant conductance G/sub cs/ in parallel with the main magnetizing inductance is

The magnetic circuit of power transformers is built with magnetic oriented grain sheet. These modern sheets present a more and more narrow static hysteresis cycle, as well as an important remanent flux density, generally larger than 1 tesla. Although

This paper describes an original numerical method for modeling rectified polyphase salient pole synchronous machines which are commonly utilized for large turbo-generator brushless excitation systems. Simulating this kind of system under normal (and
