Abstract: According to one or more embodiments, a current limiting device is provided. The current limiting device includes a transformer including: a primary winding configured to accept an input current, a core electromagnetically coupled to the primary winding, and a secondary winding electromagnetically coupled to the core. The secondary winding is configured to provide a current limiting energy source based on the input current where the current limiting energy source is limited to a predetermined maximum current based on at least one characteristic of the core.
