• Purpose – The purpose of this paper is to develop a simulation tool which permits reducing the cost of long time‐range simulation of complex converters and running at high frequency.

  Design/methodology/approach – A different method is used to represent a simplified converter but the adopted technique uses the average representation of the cell converter.

  Findings – The paper shows that the use of averaged representation of the pulse width modulation switch in multilevel converters is staying applied. The main advantage of the proposed averaged model is its simplified representation when only electrical behaviour is considered.

  Research limitations/implications – The analytical algorithm of the averaged model can be introduced in different simulator as it has a description language, enabling study of the Compatibilité Electromagnétique and electrothermal phenomena.

  Originality/value – This paper presents an averaged model of the multilevel converter which can be implemented in any simulator as it has a description language.
