Embedded electric HVDC distribution network are facingdifficult issues on quality and stability concerns. In order to helpto resolve those problems, this paper proposes to develop ananalytical model of an electric drive. This self-contained modelincludes an inverter, its regulation loops and the PMSM. Aftercomparing the model with its equivalent (abc) full model, the studyfocuses on frequency analysis. The association with an input filterhelps in expressing stability of the whole assembly by means ofRouth-Hurtwitz criterion.
