Future naval medium-voltage direct current (MVDC) power systems will contain a large number of power electronic devices. The switching events from these devices will produce undesirable effects, such as common-mode (ground) current through coupling of the power system and the ships hull. Historically, research in the area of electromagnetic characterization provides insight into common-mode and conduction currents within a specific component. However, there have been relatively few studies developed to understand the impacts of these common-mode drivers in the context of a full system. The aim of this paper is to provide further study of these system-level impacts. This paper utilizes a formalized common-mode modeling approach to further the discussion and research into common-mode issues in the system context. A brief review of the approach is provided. The approach is then applied to a representative notional two-zone MVDC simulation model.
