Method of Time-Domain Integral Equation for Solution of Field-Circuit Hybrid Problems
摘要
Abstract
Solution methods based on time-domain integral equation(TDIE) for field-circuit hybrid problems are studied, the principal idea of which is "coupling current". Circuit part and electromagnetic structure in the area are combined by the coupling current at the junction. Traditional current continuity equation is consummated by that result. Then TDIE and the simulation method for circuit - modified nodal analysis (MNA) is combined, and general Kirchoffs voltage law(KVL) is used to contact electric potential both at node of the circuit and at port of the electromagnetic structure. When this method is applied to solve hybrid problems of field and circuit, port model is no longer needed, and the coupling equations are solved directly. Finally, an example of transmission line is presented to testify validity of the method.关键词
