MONA—A magnetic oriented nodal analysis for electric circuits

The modified nodal analysis (MNA) is probably the most widely used formulation for modeling and simulation of electric circuits. Its conventional form uses node potentials currents across inductors voltage sources as unknowns, thus taking an viewpoint. In this paper, we propose alternative magnetic oriented analysis(MONA) circuits, which based on charges capacitors primary degrees freedom, giving direct access to these quantities. resulting system has structure a generalized gradient immediately ensures passivity in absence sources. A complete index presented showing regularity under standard topological conditions network interconnection. comparison MNA, differential-algebraic MONA smaller by one cases facilitates numerical solution. Some preliminary experiments are illustration feasibility stability new approach.
