Generalization of parallel analysis for a power electronic system by circuit partitioning

This paper proposes a general-purpose numerical technique of a new fast parallel circuit simulation method for a power electric system by applying an explicit integration formula to selected energy storage elements such as inductors and/or capacitors. The optimum step-size is selected for each subcircuit. A general parallel method is proposed to utilize thread processing techniques based on the OpenMP application program interfaces with a multicore CPU and shared-memory system to reduce its processing time. Its efficiency is validated by the effects of reducing numbers of time steps and circuit sizes of example circuits.
