Problems solved by technology

However, HVDC systems can present problems that do not occur in AC systems
For example, unlike AC systems, HVDC system circuit breakers can be difficult to build because typically some mechanism must be included in the circuit breaker to force the current to zero, otherwise the arcing and contact wear would be too great to allow reliable switching

Abstract

High voltage direct current systems are provided including one or more outlets and an electronic current limiter circuit associated with the one or more outlets. The electronic current limiter circuit is configured to limit current inrush when a connector is plugged into and / or unplugged from the one or more outlets when a direct current bus associated with the one or more outlets is energized so as not to damage the connector; and / or isolate direct current faults and / or excess current draw in a load connected to the one or more outlets so as to protect the system from shutdown.

Description

[0001] priority claim [0002] This application claims priority to US Provisional Patent Application No. 61 / 378,672, filed August 31, 2010, the disclosure of which is hereby incorporated by reference as if set forth in its entirety. technical field [0003] The present subject matter relates generally to high voltage direct current distribution and methods, and more particularly to high voltage electronic switches and related methods for controlling direct current arcs. Background technique [0004] As opposed to more common alternating current (AC) systems, high voltage direct current (HVDC) power transmission systems use direct current to transmit power at high volumes. HVDC systems can provide the ability to transmit large amounts of power over long distances with lower capital costs and lower losses than AC systems. Thus, HDVC systems may allow efficient use of energy away from load centers. However, HVDC systems can present problems that do not occur in AC systems. F...
