Methods and apparatus to prevent undesired triggering of short circuit or over current protection

An apparatus comprising;

• a current increase detection circuit to compare an input current and an output current and generate a current detection signal when the output current is increasing;
• a voltage detection device coupled to receive a supply voltage and an output voltage, wherein the voltage detection device generates a voltage detection signal when the output voltage increases;
• a logic gate coupled to receive the current detection signal and the voltage detection signal, and, based on the current detection signal and the voltage detection signal, generate a selecting signal;
• and
• a pulse extender to extend the selecting signal for a predetermined time to block an output of a first protection device, wherein the output of the first protection device is to cut off the output voltage provided to a load.

A system, comprising:

• a first server configured to be coupled to an input supply, the first server including:
• a load to receive power from the input supply;
• and
• a power path device to avoid generating an unwanted interrupt in supply voltage when there is no fault on the load;
• and
• a second server coupled in parallel to the first server and configured to be coupled to the input supply, wherein the second server generates an input transient across the first server.
