Efficient harmonic-based simulation of switched networks linked to nonlinear circuits

This paper presents a hybrid approach to simulate harmonic dynamics of switched networks connected to nonlinear electrical devices. The proposed approach relies on i) representation of the switched part of the network via generalized averaged models (GAM) and ii) modeling of the nonlinear part of the network via extended harmonic domain (EHD). It is shown that computational savings are achieved by the proposed hybrid approach compared to a complete EHD system modeling while preserving GAM and EHD features in the corresponding solution variables.
