System-level construction of multiconductor transmission line inductance matrix

Classical methods usually adopt micro-elements analysis to compute MTL (multiconductor transmission line) inductance matrix, which are complex and time-consuming. To solve the problem, a novel method used to construct MTL inductance matrix on system-lever is proposed. Novel method chooses wire rather than micro-element as the unit for analysis to simplify calculation, and expressly describes the relation between inductance of isolated two-wire and inductance matrix. Simulations show that the novel method is as accurate as classical methods, but the time-cost is much smaller than classical methods´.
