    Novel Feedback Theory of Electric Circuits—Part I: Cut-Based Decomposition

    No full text
    In this paper and in its companion, a novel cut-based decomposition for transfer functions of linear time-invariant circuits is introduced and an invariance property, with respect to the cut, is proven for the set of quantities introduced by this cut-based decomposition. These results naturally lead to a novel feedback theory of electric circuits which, unlike Bode's feedback theory, is based on the unambiguous decomposition of transfer functions. Such feedback theory provides a natural extension to the elementary model of feedback amplifiers based on block diagrams, from system theory to circuit theory, and a natural extension to Blackman's formula

    Corona Discharge Simulation of Multiconductor Electrostatic Precipitators

    No full text
    The paper considers corona discharge problems with multiple conductors, such as those appearing in some electrostatic precipitators. A common, precise condition is identified in which previous approaches proposed in literature fail. For dealing with these conditions, a novel formulation of the problem is proposed. Moreover, a Newton-Raphson scheme is defined for iteratively solving a non-standard Petrov-Galerkin Finite Element discretization of the problem. The presented approach is validated on a benchmark for which an analytical solution is known
