The theoretical foundations of linear circuit theory rest on Maxwell’s theory of electromagnetism. In its more applied form, circuit theory rests on the key concepts of Kirchoff’s Laws, impedance, Ohm’s Law (in its most general sense by encompassing impedances), and the Principle of Superposition. From this foundation, any linear circuit can be solved: Given a specification of all sources in th...

As described in my previous paper [1], the voltage-source equivalent was first derived by Hermann von Helmholtz (1821–1894) in a 1853 paper [2]. Exactly thirty years later in 1883, Léon Charles Thévenin (1857–1926) published the same result [3, 4] apparently unaware of Helmholtz’s work. The generality of the equivalent source network was not appreciated until forty-three years later. Then, in 1...

This report addresses the issues concerning analysis of an electric circuit composed multiple resistors configured in a 3-Dimension structure. Noting, all standard textbooks physics and engineering irrespective used components are circuits assembled two dimensions. Here, by deviating from “norm” we consider case where arranged 3D structure; e.g., cube. Although, independent dimension design sam...

In this paper, we propose a design method for novel motor using magnetic resonance coupling (MRC) to enable the practical use of electric aircraft. The proposed can transfer electrical energy between stator and rotor via MRC, which does not require cores, thus realizing an ultralightweight design. Moreover, detail operating characteristics its equivalent circuit, analysis, experiments. From cla...

electric power industry have always try to provide reliable electricity to customers and at the same time decrease system costs. high voltage circuit-breakers are an essential part of the power network. this study has developed a maintenance and replacement scheduling model for high voltage circuit- breakers that minimize maintenance costs while maintaining the acceptable reliability. this mode...

Broadband electromagnetic (EM) modeling increases in importance for virtual prototyping of advanced power electronics systems (PES), enabling a more accurate prediction fast switching converter operation and its impact on energy conversion efficiency EM interference. With the aim to predict reduce an adverse parasitics dynamic performance semiconductor devices, circuit-oriented based extraction...
