APPARATUS, SYSTEM, AND METHOD FOR ERROR DETECTION IN A STAND ALONE POWER SUPPLY
First Claim
1. An apparatus for error checking in a power supply, the apparatus comprising:
- a power module that determines that a power supply is in a self-test condition, wherein the self-test condition comprises the power supply being connected to an input power source and the power supply being disconnected from an electronic load;
a load module that connects a test load to the power supply in response to a determination by the power module that the power supply is in the self-test condition, wherein the test load is internal to the power supply;
an error checking module that performs one or more error check operations on the power supply connected to the test load, wherein the error check operations determine the presence or absence of one or more faults in the power supply; and
a notify module that actuates an indicator in response to the error checking module determining that one or more faults are present in the power supply.

Abstract
An apparatus for error checking in a power supply includes a power module that determines that the power supply is in a self-test condition. The self-test condition involves the power supply being connected to an input power source while it is disconnected from the electronic load that it normally services. A load module connects an internal test load to the power supply when the power supply is in self-test condition, and an error checking module performs error check operations on the power supply while it is connected to the test load. The apparatus also includes a notify module that actuates an indicator when the error checking module determines that there are one or more faults in the power supply. The apparatus may also include a log module for storing error messages and reports in non-volatile memory.

10. A system for error checking in a power supply, the system comprising:
-
a power supply that provides a regulated output voltage to an electronic load; a test load that provides a predetermined level of impedance, wherein the test load is internal to the power supply; a power module that determines that a stand-alone power supply is in a self-test condition, wherein the self-test condition comprises the power supply being connected to an input power source and the power supply being disconnected from the electronic load; a connection module that sends the power module a self-test signal in response to the power supply being disconnected from the electronic load; a load module that electrically connects the test load to the power supply in response to a determination by the power module that the power supply is in the self-test condition; an error checking module that performs one or more error check operations on the power supply connected to the test load in response to the load module electrically connecting the test load, wherein the error check operations determine the presence or absence of one or more faults in the power supply; and a notify module that actuates an indicator in response to the error checking module determining that one or more faults are present in the power supply. - View Dependent Claims (11, 12, 13, 14)
