Purpose – The purpose of this paper is to synthesize equivalent circuit obtained from reduced order model of large scale inductive PEEC circuits. Design/methodology/approach – This paper describes an original approach for reducing and synthesizing large parasitic RLM electrical circuits coming from inductive Partial Element Equivalent Circuit (PEEC) models. The proposed technique enables the re-use of the reduced order model in the time domain circuit simulation context. Findings – The paper shows how to use a synthesis method to realize an equivalent circuit issued from compressed PEEC circuits. Originality/value – The coupling between methods PEEC and a compressed method as Fast Multipole Method in order to reduce time and space consuming are well known. The innovation here is to realize a smaller circuit equivalent with the original large scale PEEC circuits to use in temporal simulation tools. Moreover, this synthesis method reduces time and memories for modelling industrial application while maintaining high accuracy. [ABSTRACT FROM AUTHOR]

Purpose – The aim of this paper is to model time-harmonic problems in unbounded domains with coils of complex geometry and ferromagnetic materials. Design/methodology/approach – The approach takes the form of a coupling between two integrals methods: the magnetic moment method (MMM) and the partial element equivalent circuit (PEEC) method. The modeling of conductor system is achieved thanks to PEEC method while the MMM method is considered for the magnetic material. Findings – The paper shows how to use the MMM/PEEC coupled method to model a problem comprising conductors and ferromagnetic materials and compare its results with the FEM and the FEM/PEEC coupling. Originality/value – The two methods PEEC and MMM are well-known. The innovation here is coupling these methods in order to take advantages from both methods. Moreover, the performances of this coupling are studied in comparison with others (FEM, FEM/PEEC coupling). [ABSTRACT FROM AUTHOR]
