Real-time simulation of a twelve-pulse full converter

Within this paper, a method for the real-time simulation of a twelve-pulse full converter is described. The method is based on a finite-difference simulation of the homogeneous state model of the converter with the inputs clamped over an integer multiple of solution time steps. The simulation code described was written in FORTRAN and executed on IBM RISC System/6000 machines. The computation time required for each simulation time step was 40 μs, which satisfied the real-time constraint. The resultant code is suitable for inclusion in a system-level simulator where multiple subsystems are simulated in parallel on multiple processors.
