Apparatus and systems for common mode voltage-based AC fault detection, verification and/or identification

摘要

Apparatus for AC fault (ACF) detection are provided. In addition, apparatus for AC fault (ACF) detection and verification are provided. In addition, apparatus for identification of a module which is the cause of an AC fault (ACF) are provided. In one implementation, one or more of these apparatus can be combined to provide a fast, simple, low cost and reliable ACF detection, verification and/or identification circuit.
