The MT9-PC part of Microtran is a program which can be used to analyze and model the performance of electrical systems and components. It is used to create design models of linear, non-linear, or dynamic systems. The program uses a finite element solver and can be used to develop control systems, study system stability, analyze power flows, determine optimal operation points, and investigate system performance. It provides powerful and intuitive tools to allow the user to develop complex models quickly and accurately.
