Automatic circuit partitioning for parallel simulation of a power electronic system

This paper describes a parallel circuit simulation method which divides the whole system into subcircuits by applying an explicit integration formula to selected energy storage elements such as series inductors and/or parallel capacitors. A new automatic partitioning method of a system into subcircuits is proposed. The method mainly consists of two steps; detection of parallel capacitors and series inductors with consideration of control circuits. The proposed method is applied to power electronic systems. It is investigated how the proposed method works and shown for effectiveness of parallel simulation by the circuit partitioning.
