Abstract:
1. An apparatus for detecting a failure of a power system, the apparatus comprising: an input power detection module that detects an amount of input power provided on a power supply side of a connector, the connector configured to connect a switching power supply to a load such that power flows from the switching power supply to the load through the connector; an output power detection module that detects an amount of output power provided on a load side of the connector; a failure detection module that determines if the amount of input power detected on the power supply side of the connector is more than a predefined threshold amount greater than the amount of output power detected on the load side of the connector; and a shutdown module that shuts down the switching power supply in response to the failure detection module determining that the amount of input power detected on the power supply side of the connector is more than the predefined threshold amount greater than the amount of output power detected on the load side of the connector.
